Computer fault as well as solution encyclopaedia

The fault reason that computer arises is puzzling, let one be hard to ponder. And since the package of Windows operating system is relatively complex, computer once appearance fault, for ordinary user, the reason of wanting to find out its fault accurately is nearly impossible. So whether say us if the time of meeting computer fault , have you felt quite helpless completely? Actually, is not so , make the reason that computer produces fault though have a lot, but so long as we observe carefully, summarize conscientiously, we may grasp some laws of computer fault and the methods of handling still. The pamphlet in this issue in, we will some most common is also the diagnosis of the most typical computer fault , maintenance method demonstrates to you, pass through it, you will discover that - - solves computer fault method when your side, it is simple, but effective!

One and

Mainboard is the crucial parts of entire computer, from computer the most important role. If mainboard produces fault, will influence the work of the entire system of personal computer. Following, we see mainboard together the most common fault in the process of using has which.

Common fault

Computer start has no to show , first, what we will inspect is BIOS. In BIOS of mainboard, store important hardware data, at the same time, BIOS is also more fragile and partial in mainboard , is easy to get damage very much, once being damaged , will cause system to can not run , even appearance is this kind of, as fault, is because mainboard BIOS is broken by CIH virus to cause ( also do not remove the very mainboard certainly fault causes system to can not run. ). After virus destroies general BIOS, the data in hard disk will be lost completely, so we may pass through the detection data of hard disk whether intact come to judge whether BIOS had been destroied , if the data of hard disk is excellent without damage, 3 kinds of reason can cause start to have no the phenomenon that shows:

1. Because mainboard development groove or

2. Do not jump line mainboard the CPU frequency installed in CMOS incorrect, may also cause do not show fault, for this, so long as clearing away CMOS, can solve. Clear away CMOS jump line is nearby the lithium battery of mainboard normally , it acquiesces in that location is shorted normally for 1 and 2, so long as altering it to jump for 2 and 3 short circuits, some seconds of kinds can solve problem, it is taken off that for former old mainboard if jump if user can't seek , line takes battery only after, show till start to enter CMOS installation close again machine, will battery the very best purpose that also reaches CMOS discharge.

3. Mainboard can not distinguish memory, memory damage or memory do not match can also cause start to have no the fault that shows. Some old mainboards are stored relatively in fastidiousness, once inserting mainboard, the mainboard and memory that not distinguished can not start , even some mainboards does not point out to your any fault( ringing shouts ). Certainly at also some time, can cause the appearance of this kind of fault also to store in expansion with the memory that raises systematic performance and inserts different brand and type as a result, therefore when overhaul, should mark Yi.


For the fault that mainboard BIOS has been destroied , we may insert ISA to show card , see whether show ( if have hint, may according to hint step operation can. ), if have no start frame, you may do one by oneself to update the floppy disk of BIOS voluntarily , refresh BIOS again, but after some mainboard BIOS has been been broken , soft Qu foundation not works , right now, try to use heat insert the law of pulling out to solve ( I have tried, so long as BIOS is identical, in the mainboard with rank, may burn record successfully. ). But insert with heat to pull out BIOS with identical needs outside may still cause mainboard partial component damages, so reliable method uses to write yard ware update BIOS file writes in BIOS inside( may seek the computer business solution that has this service to compare safety ).
銆€銆€
Common fault 2: It
As this kind of fault, is since mainboard battery voltage is insufficient to cause , change for this can, but after some mainboard battery is changed , also, can not solve problem , has two possibilities right now:

1. Mainboard circuit problem,

2. Mainboard CMOS jumps line problem, have time because of mistake will CMOS on mainboard jumps line sets up to clear away to choose item , or installation becomes outside receive battery, make CMOS data can not preserve.

Common fault 3: After Windows takes off installation

On some mainboards of less known brand sometimes, can arise this kind of phenomenon, after pack mainboard driver over, start computer again can not enter the tabletop of Windows 98 with normal pattern, and this driver can not be uninstalled under Windows 98. If arise this kind of condition, suggest to find newest drive to install again, as problem, can solve , if do not be all right really, can only install again system.

Common fault 4: Install Windows

As the software reason that arises this kind of fault being since CMOS installs mistake arouse. The management fence of power source installed in CMOS has a project of modem use IRQ, he choose difference is 3 , 4 , 5. . . . .. , NA, general it acquiesce in to choose item is 3, installing it for the suspension item besides 3 can.

Common fault 5: Computer halts frequently

In CMOS, occur the phenomenon of halting , have problem

Appearance is as this kind of fault since mainboard Cache has problem or mainboard design scattered heat bad arouse, the author has discovered on the mainboard of 815 EP that causes the phenomenon of this fault since mainboard scattered heat is not enough good. After halting , touch CPU around mainboard component , discover its temperature to scald hand very much. When change big power fan afterwards, halt fault has solved. For Cache has the fault of problem, we may enter CMOS installation , can solve problem smoothly after prohibiting Cache , are natural, after Cache prohibits , speed can surely get , have influence.

Common fault 6: Mainboard

Arising this kind of fault normally inserting since user is electrified to pull out related hardware cause , right now, user may replace with muti-function card, must but prohibit mainboard first before replacing go up is from COM of tape and parallel mouth( some mainboard even IDE mouth will prohibit to be able to use normally ).

Show
Common fault

As this kind of fault, it is bad to be because show card and mainboard contact or mainboard slot has problem to cause. For some integrations show the mainboard of card, if show to store common main memory , need to notice the location of memory bar, normally on the first slot of memory bar, insert have memory bar. Since showing card, the start that reason causes has no to show fault , after start normally, can send the bee ringing sound of short a long two ( show card for AWARD BIOS).

Common fault 2: Show

This kind of fault general is because of display or show card do not support high resolution ratio cause. When spending screen, switch to start pattern go to safe pattern , then enter again under Windows 98 to show that install , choose under 16 color states" application" , determine button. Start again , delete under 98 Windows systematic normal patterns to show to block driver, start computer again can. Also may do not enter safe pattern, edit under pure DOS environment
SYSTEM, INI file, will display, drv=pnpdrver alters , is display, after drv=vga
Driver.

Common fault 3: Color shows
1. Display card and
2. Display
3. When runing in some softwares, color is not normal
4. Show card
5. Display quilt is magnetizing, this kind of phenomenon general is since and have magnetic can object is close excessively to deliver after, magnetizing return may arouse show that frame arises the phenomenon that turns.

Common fault

Arising this kind of fault see normally in mainboard and show card is not compatible or mainboard and show card to contact is bad; Show card expand card with other not compatible also meeting cause halt.

Common fault 5: Screen

As this kind of fault being since show card show
Block.

Common fault 6:

Showing to block driver year enter , after runing a time, driver loses voluntarily, as this kind of fault, it is not good to be since show to block quality or it is not compatible to show card and mainboard, it is too high to make show to block temperature , so, cause system to run instability or appearance to halt , only change right now to show card.

Besides, there is still a kind of special condition, before, carrying to enter to show block driver, but when showing card after driver year is entered , when entering Windows, appears to halt. May change other model show card when after year enters its driver, insert to enter old show card to solve. If if can not still solve this kind of fault, explain registered table fault , show for registration to carry out recovery or new installation operating system can

Sound
Common fault one: Sound card

1. Driver acquiesces in that output is " quiet sound". Click screen the sound little icon of right next angle( little Sou Ba), under arise volume regulation slide block, " quiet sound " choose item, click the check box of front edge , clear away frame check , can normal pronunciation.

2. Sound card and other insert card have conflict. The method of solving is the systematic resource that adjustment PnP uses for blocking , makes each card not to disturb mutual. Sometimes, open " equipment management" , although do not see yellow exclamation mark( conflict sign), but sound card is not sound production, actually, it is also to have conflict, but system has no inspection, comes out.

3. Have installed Direct X rear sound card can not sound

4. A sound road is silent. Inspection

Common fault 2: The noise that

1. It is straight that inserting block. Is not enough to be sound card high since box makes precision , sound card outside baffle manufacture or installation bad cause can not combine with mainboard development groove closely, visual evidently the development groove spring flat " golden finger" on sound card has offset. This kind of phenomenon has on ISA card or PCI card , belongs to common fault. Normally, may correct with pliers.

2. The source input of sound box receives when the Speaker
The no merit on sound card is put , noise will be more little. On some sound card, have only a export end, is Line out or Speaker will lean card go up jump line decision, the way of acquiescing in of manufacturer is Speaker frequently, will so pull out sound card to adjust to jump line.

3. Windows is not good from the driver of tape. When
" Windows acquiesces in driver " install if using the way of " add new hardware " to select " from magnetic disc installation " and do not select from list box. If have installed Windows from the driver of tape, may choose " control face plate system equipment management sound, video and game controller " , divide equipment each in point , choose " attribute driver change driver from magnetic disc installation ". Now is inserted into compact disk or the magnetic disc with additional sound card , is packed into the driver that manufacturer offers.

Common fault 3: Sound

1. Use new driver or replacing program as far as possible. The author has had a sound card, coil under Windows 98 with original drive to install driver pack anyhow not go up, have to replace with the driver of Creative SB16, everything is normal. Afterwards, promote Windows Me, it is just normal that again not change normally again to use Windows2000( complete edition) from the sound that brings block driver.

2. The problem of most having a headache not too Windows 9 X next detection goes to plug-and-play equipment take matters into one's own hands deliberately to help you installation driver, this driver can not use , afterwards, being you every time to delete pack again, can repeat this problem, and can not solve with the method of adding new hardware. The author reveals a only door here, is dense to recruit: Enter Win9xinfother catalog , check on in the * of sound card, the file of +INF trillion deletes completely install again again after starting with by hand, this is totally efficacious, have rescued countless sound to block life , , , certainly, even modification is registered, table can also reach same purpose.

3. Do not support the installation of PnP sound card( also apply to PnP that can not have to state PnP way installation sound card): Enter " control face plate" / " add new hardware " / "next step", when hint " needs Windows search new hardware? " , select " Fou ", then select " sound, video and game controller" to coil or select directly sound card with drive from list type installs.

Common fault


1. It is completely silent. Use Windows 98 " CD play ware" put CD is silent, but it is normal that " CD play ware " again work , this explanation is that the line of audio frequency of CD driver has not set. Use a 4 core line connections of audio frequency CD - in on the simulated export harmony card of audio frequency of CD - ROM can, this line when purchase CD - ROM meeting is additional.

2. Only a sound road makes sound. As the export mouth of CD driver, control two line signals, intermediate two lines are ground wire. Since the 4 line color of the line of audio frequency is normally different , may find 11 from the color of line to reply interface. If sound has only a interface or every interface and the line of audio frequency on card, does not match , has to change the wiring order of the line of audio frequency, usual 2 line as change can.

Common fault 5:

Normally, being because PCI shows card to adopt the technology of Bus Master cause the hard disk that hangs on PCI bus line to read to write , the operations such as mouse move have magnified background
The cause of noise. Solution method: Closing PCI to

Common fault

First inspect microphone whether in have mistake to insert go to other to insert hole , secondly, click double little trumpet, choice chooses sheet " last attribute recording ", see whether every installation is correct. Then in " control face plate multi-media equipment ", adjust " mixer equipment" and" line input equipment", set up them to use state. In if " multi-media audio frequency " "recording" chooses item is grey and that may go bad , certainly, it is also not the room not saved , you may try " add new hardware systematic equipment " in add "ISA Plug and Play bus", following sound card without hesitation to block tool software start again after installing.

Common fault 7: Can not

The phenomenon of can not play Wav music is more rare, often because of" multi-media" "equipment" " take off audio frequency equipment " not a , prohibit to use one can; Can not play MIDI file may have 3 kinds of following possibility:

1. Early ISA sound card possibility is because of 16
Way should

2. Now, popular PCI sound card composes technology mostly with wave table, if MIDI part can not sound reproduction shows tone color very probably because you have no wave with proper load addition storehouse.

3. The MIDI passageway in Windows

Common fault 8: PCI sound

Some users reflect , when sound blocks driver to install , in process, everything is normal , has not also arisen equipment conflict, but under WIN98 can not make sound or appearance other faults. This kind of phenomenon usually appears on PCI sound card, please in inspection a next installation process you insert PCI sound card when which PCI slot go up. Some friends like to insert sound card in view of the consideration of scattered heat, is being far away from AGP slot , is near some of that PCI slots of ISA slot. Problem often appears here, because Windows98 has a Bug: Sometimes, can only distinguish correctly insert in the sound card of PCI - 1 and two PCI - 2 grooves. And on ATX mainboard, it is just PCI - 1 and PCI-2 to lean two PCIs of AGP tightly( is just opposite on some ATX mainboards, what lean ISA tightly is that PCI-1), so if you have not installed PCI sound card on correct slot, problem will produce.

Hard
Hard disk is the storehouse of software of the information taken the responsibility for to stock us, the fault of hard disk can often cause system if handling improperliness can not start and data lose , so, when the common fault of how we should deal with hard disk?

Common fault

System can not start from hard disk , can not also enter C plate since A plate starts , use the automatic inspection function in CMOS can not also discover the existence of hard disk. This kind of fault appears mostly, is joining cable or IDE port , the very hard disk the possibility of fault is not large, may carry out replacement experiment through inserting again to receive the change IDE mouth and cable etc. or cable of hard disk , will discover the place of fault very quickly. If the hard disk that receives recently had been also not accepted , a common reason is the principal and subordinate on hard disk jump line, if a IDE line of hard disk goes up receive the two equipments of hard disk, will distinguish Chu the relation of principal and subordinate.

Common fault 2: Hard

As this kind of fault being since CMOS installs fault arouse. The type of hard disk in CMOS is correct and Fou direct influence hard disk use normally. Current machine supports the function of " IDE Auto Detect " , may the type of automatic detection hard disk. When the type of hard disk is wrong, sometimes, can not start system straightforwardly , can start sometimes, but meeting occur read to write mistake. For example, the type of hard disk in CMOS is smaller than the actual capacity of hard disk, the fan district behind hard disk will not read to write , if is many zone states a few of zones will lose. There is still a important fault reason, because of now IDE support logic parameter type , hard disk may adopt " Normal, LBA, Large " etc., if have installed under general pattern data, and alter in CMOS is other pattern, can occur hard disk read to write wrong fault, because it has been changed that it shines upon relation, will not read to take the original correct location of hard disk.

Common fault
It is usually based
1. Main bootstrap
2. Zone table
3. Zone effective
4. DOS guides
In which, it is simple that DOS guides file to damage , it is rear that using to start coil to guide , transmit a guide to system file may. Main bootstrap damage and zone effective position damage may also force with FDISK / MBR normally to cover to write solution. Zone table damage is troublesome , because can not distinguish zone, systematic meeting is hard disk one do not the naked a plate of handling of zone, therefore cause some softwares to can not work. Have simple method - - use however Windows2000. Seek to have Windows 2000 system, go up the of hard disk of damage after, start, since Windows 2000 for guarantee systematic hardware
Stability meeting carry out scanning for receiving recently
There is very good restoration

Zone table damage still has a kind of form, here, I call tentatively " zone shines upon ", specific expression is a appearance and campaign the zone as zone. It is the same to include file structure, content and zone capacity. If when arbitrary district binary district content has made change, metropolis when another embodiment comes out , seemingly is the shadow that shines upon is the same. I have met , the hard disk of 6.4 G becomes 8.4 G( the C district that has shone upon 2 G ). This kind of problem is especially embarrassed, this problem does not influence use, do not restore will not also have no time , will but restore , PQMAGIC and DISKDOCTOR of NORTON have become to open eye , is blind, binary district total capacity and the reality of hard disk size is not uniform to look but see not , have no problem profusely is perfunctory to you. Deal with this problem, have only GHOST to cover and use the salvation a plate of recovery of NORTON zone table.

Common fault

This is makes one shocked, person sees the word that person is afraid of. Recently IBM public praise also declines steadily therefore. Scanning program SCANDISK of magnetic disc that is you to use systematic Windows system from tape scanning hard disk time, system hint says that hard disk may have bad road, have dodged soon afterwards a terror is blue, a square piece of Xiao Huang slowly extend open, then, on certain square piece, have been marked a . . . . . of " B ".

Actually, these bad roads are logic bad road mostly , may be restored. Do not need at all to send to repair( allegedly manufacturer develops the tool of self check is because cannot bear the half foundation in the hard disk of repair is this good fact " it is cruel").

So, the time when the problem

Once with "SCANDISK", scanning spoils it is of hard disk if program hint has got to say , first, we should use each brand own program of hard disk of self check again to carry out complete scanning. Notice is other to choose fast scanning, because it can only check out the problem of approximate 90%. Let self rest assured , when this many flowers some time is been worth for.

If the result of inspection is " successful restoration", that may determine that is logic bad road , may pat chest pant tone; If being not, that is not as possible as what restoration , if your hard disk is returned in shelf-life, that hastens , is that to change.

Say since logic is bad has made cluster number mark, afterwards, do not distribute to file to use. Say badly if being logic, only will the new form of hard disk melts may. But melt to prevent form the possible phenomenon of abandoning ( show because of having made mark on cluster number is bad cluster, form melts program possibility no inspection has accepted " this reality ", so abandon this cluster), the best still heavy zone uses , is still pretty rapid as the software of the etc. of IBM DM, or GHOST covers also may, merely this two schemes can lose some data somewhat.

Common fault 5: The

Generally speaking, after the form of hard disk melts , capacity will be smaller than nominal value, but this gap will not absolutely exceed 20%, if two gap is great, should when start enters BIOS installation. It is in which making reasonable installation according to your hard disk. If still not be all right explaining possibility is your mainboard does not support the hard disk of high capacity, right now, may try mainboard BIOS with newest download and refresh solution. This kind of fault appears when the more old mainboard and hard disk of high capacity are arranged. Is other, since break suddenly news etc. reason makes BIOS installation produce confusion may also cause this kind of fault occur.

Common fault 6: No matter

This kind of fault general is because of hard disk quilt the lock " logic lock" of virus lives to cause , " the logic lock of hard disk" is a kind of very common mischief means. In logic lock afterwards, no matter using what equipment, can not guide system normally , is even floppy disk , CD driver and two hard disks the same no any role.

" logic lock" go up lock principle: Will search for the order of all logic plate when computer guides DOS system , when DOS had been guided , first, will go to seek main guide to fan the zone table message of district , then seeks the logic plate of each development zone. " logic lock " have modified normal God to guide zone record , will expand the first logic a plate of directional self of zone , make DOS seek next logic plate after seeking first logic plate when starting to always find self, circulate so as soon as having formed to die.

It is the power source of hard disk " it is hot to pull out to insert" to untie the method with more easy lock to" logic lock". Is when when system starts , do not give first is added by the hard disk of lock
Electricity, give hard disk again after starting completion to" be hot to insert " last power supply cord, so, system may be normal to control hard disk. This is a kind of very dangerous method, to reduce dangerous degree, after meeting " logic lock", all had better handle according to some kinds of following more simple and safe methods.

1. First, prepare one to start plate , then use the editor tool of binary system( recommendation UltraEdit) on other normal machines to modify IO on floppy disk , SYS file before( modification remembers alter the attribute of this file first is normal), specific is searching for the first string of " 55AA " inside this file , after finding modifying for any other number values can. Using this modification the system of error floppy disk you may smooth region is started by the hard disk locked. However now because of the normal zone table of this hard disk, have been destroied , you can not delete and modify zone with "Fdisk", now, you may use the software recoveries such as Diskman or reconstruction zone can.

2. Because DM is the tool of hard disk that does not rely on mainboard BIOS to distinguish hard disk, in mainboard BIOS set up hard disk is " NONE", DM may also distinguish hard disk and carries out zone and form melts etc. operation, so we also may with a view to untie lock with DM software as hard disk.

First will DM Kao go to a system to coil go up, receive
After preserving , " NONE " quit , then start system with floppy disk, system can" tape lock" start , because of right now systematic foundation is equal to no hard disk. After starting , run DM, you will discover that DM may distinguish hard disk in, choose this hard disk carries out zone form to melt may. This kind of method simple convenience however has a fatal shortcoming, is the data on hard disk most likely

Common fault 7: At the

This kind of fault often most makes one feel fearful. It had been destroied that the major reason that produces this kind of fault is that God of hard disk guides fan district data, expression guides sign or zone sign for God of hard disk to lose. The chief offender of this kind of fault is often virus, its data of be wrong has covered God, guide fan district. Some common antivirus softwares on business have offered the function of restoration hard disk , all not Fang a examination. But coil if having no this kind of tool on hand, may try write 0 whole datas to take the post of guide fan district, then, new zone and form melt , its method is as follows: Start plate with a clean DOS to start computer , enter A: After \ >, input in order to order ( bracket for explanatory note):
DEBUG( enter DEBUG program)' >A: \ > DEBUG( enter DEBUG
- F100 3FF0( settle the
- A400( the order
MOV AX, 301
MOV BX, 100
MOV CX, 1
MOV DX, 80
INT13
INT03
- G=400( execution for
- Q( return DEBUG

Can make your hard disk revive normally with this kind of method , but melt because of wanting new zone and form, the data of inside may be protected for disaster. Above is solution method and some common faults of hard disk in daily use, hope can arouse for all. If the fault of hard disk is pretty serious, when can not have some method handlings stated , is mechanical fault very probably. Since the structure of hard disk is pretty complex, so, does not suggest user to dismantle by oneself , and should ask for help in professional to give repair.

Memory


Memory is the one of most important accessory

Common fault

The reason of memory bar appearance this kind of fault general is in memory bar and mainboard store slot contact is bad to cause , so long as with rubber, rubing back and forth to rub examination , its golden finger position can solve problem( do not wash with alcohol etc.), it is memory damage to still have or in mainboard, storing groove have the problem that can also cause this kind of fault.
Cause start to have no to show fault because of the

Common fault 2: Windows registered

This kind of fault general is because

Common fault 3: Windows

As this kind of fault, is since mainboard and memory bar are not compatible or the quality of memory bar not good arouse, common the memory of the rate of high frequency is used in some do not support the mainboard of this frequency memory bar, trying in CMOS installation to reduce memory read to take speed to see whether solve problem , if if do not be all right , that only changes memory bar.

Common fault

As this kind of fault, is since have adopted the
Machine, for this, may reduce memory speed in CMOS installation to solve , otherwise, have use only same model memory. Still have a kind of possibility is memory bar is not compatible with mainboard, as this kind of phenomenon, see less , may be also memory bar additionally and mainboard contact bad arouse computer randomness to halt. 1

Common fault 5: After

This kind of phenomenon general is because of mainboard and memory not compatible arouse, common the memory memory bar of the rate of high frequency is used in some do not support the mainboard of the memory bar of this frequency, after the fault appearance you may try in COMS get the speed installation of memory to low point try.

Common fault 6: When runing

This phenomenon general coil because of system
Around 300

Common fault 7: Guide installation Windows

As this kind of fault, is since user has joined emm386

CD
CD driver is the one of accessory with minimum service life in computer hardware. Actually many CD drivers of discard still have greatly use value, outline tiny repair one takes off may. This need not often have what advanced radio professional knowledge , need not also use what too complex repair tool and material. You only observe carefully some methods of removing that fault phenomenon refers to execution beneath, believe your old CD driver can recover still in the past "elegant demeanor".

Common fault one: The

This is a kind of false appearance , is not so actually. It is because CD driver and hard disk receive together on a IDE interface that the lamp of hard disk twinkles , the work of compact disk the result of having also controled the lamp of hard disk. May receive the unit of CD driver on a IDE interface alone.

Common fault 2: Under Windows environment as CD

Very obviously, the 32 accesses of magnetic disc of Windows
It is halted that the 32 access functions of magnetic disc of Windows make Windows have produced internal mistake. After entering Windows, in" main crowd groups", click double " control face plate" , enter " 386 strengthens pattern " to install , click "change" again after clicking the button " store in fictitious" , close the verified frame " 32 magnetic discs are visited " of left next angle , start Windows again again after confirming , visit CD - ROM again in Windows enter will not make mistakes mistake.

Common fault 3: CD driver can not be normal to read plate,
READY READING DRIVE X ABORT.RETRY.FALL? " get in and out box occasionally

Under this condition, should first detection virus, go on with antivirus software as complete machine check to kill virus , if have not discovered virus edit software with file to open C a plate of root catalog next CONFIG.SYS " file, check in which whether again hang polishing driver and driver whether had been destroied , and handle , in may still use text editor software check to" be "AUIOEXEC.BAT"" file whether have " MSCDEX.EXE/D: The m of MSCDOOO /: 20 / V ". If above two steps does not discover problem, detachable CD driver is repaired.

Common fault 4: When CD

Most of this kind of phenomenons are to have not still taken the place when changing plate to, for CD driver, carry out the fault aroused by operation. For CD driver have operation necessary will wait for until the indicator light of compact disk shows is for good position may just carry out operation. When play video disc should also adjust time zero hour changes plate again, so, may avoid to arise above-mentioned mistake.

Common fault 5: When playing

Inspection a next AUTOEXEC, the "SMARTDRV" in BAT file whether put
Go to MSCDEX before, EXE; The high speed leading party

Common fault 6: CD driver when

CD driver reads the hardware that plate does not make fault major concentration on laser first package, and may divide into 2 kinds of condition: A kind of is that use causes laser pipe old too for a long time
Melt; Another is photoelectron surface too dirty or laser pipe lens are too dirty and displacement warps. So when adjusting for laser pipe power, it need to be still for photoelectron wash with laser pipe lens.

The method of washing of photoelectron and focusing lens is: Pull out to join a group of flat cable of laser first package , remember direction , open laser first package. Now can see sheath cover laser first focusing lens, can discover after removing sheath focusing lens from 4 thin copper wires join to focusing , seek mark coil, photoelectron package installation when under lens in just Xiao Kong. Touch few distilled waters with the cotton on the thin pack of iron wire to polish ( cannot polish photoelectron and focusing lens surface with alcohol), see lens whether level hangs in the air is being in charge of for laser, otherwise must adjust properly. Till then, wash work to be completed.

Adjust laser first power. When the side of laser first package has one picture the little potentiometer of cross screw. Take off its initial location with color notes, spin normally first along hour hand 5 machine examination machine 10 , pack do not be all right again counter-clockwise revolving 5 to coil 10 , until can read smoothly. Paying attention cut , cannot spin too many, burn out photoelectron too in order to avoid power.

Common fault 7: Start

This may be since the data line joint of CD driver
Wait , we should first inspect the data of CD driver line joint whether is loose, if discovery has not been inserted , inserts it again well , inserts. If so can not still solve fault, we may seek a new data line, change to try. At this time if the words of still existent fault, we need to inspect compact disk jump line installation , if have mistake, change it can

Mouse
Repair and the fault analysis of mouse are more simple, the most of faults are interface or button contact is bad , broken line and mechanical location systematic dirty dirt. Few fault is mouse internal components and parts or circuit is empty to weld , this exists mainly in some inferior products, in which You so as give out light diode and IC circuit damage are in the majority.

Common fault

1. Mouse thorough damage,
2. It is bad that mouse and the connection
3. This kind of condition or the 2 damages of PS / and the string mouth on mainboard are seldom seen , if is this kind of condition, have to go to change a mainboard or use the string mouth on muti-function card.
4. Mouse line contact is bad, this kind of condition is most common. The point of bad contact is in the connection of mouse built-in electric wire and circuit board. Fault is repaired only, normally but for the joint place of PS / 2 easily. Usually, is since line is shorter , or compare the disorderly reason and that causes mouse line to have been made efforts to drag , solution method is to open mouse , use electric iron again will weld spot welding well. It is bad mouse line internal contact to still have a kind of condition, is since time length causes , this kind of fault that ageing arouses to be hard to usually seek , it is the most rapid solution method to change mouse.

Common fault 2: Mouse

The flexibility of mouse drops , mouse indicator does not be wanted as so following heart before , but has obtuse reaction, location is not accurate , or can not move straightforwardly. This kind of condition major is because of the mechanical location in mouse roll axle goes up have gathered too much dirt cause transmission ineffectiveness , cause roll is not flexible. The focal point of repair is put on the main transfer machinery of mouse built-in X axle and Y axle. Solution method is to be able to open sticky ball lock flat, will mouse rolls ball unloads , using clean cloth dip in neutral detergent, wash sticky ball, friction axle etc. may use to adopt alcohol , rub to wash. Had better drip in the place of axle center on few drop oils of sewing machine , but must be careful , do not flow out friction surface and yard a plate of railings seam. Clear away all dirts after, if the flexibility of mouse recovers , is first.

Common fault

1. Mouse button has no movement, this may be because the micro-gap switch distance on mouse button and circuit board is too far or clicks switch to pass the use of a time and rebound ability drops. Open mouse, when mouse button glue the plastic flat of moderate a thickness beneath, thickness will determine according to actual needs that handling can be used after being completed.

2. Mouse button can not be sprung normally, this under possibility is because pawn button the bowl shape contact segment in micro-gap switch split arouse, after using for a long time especially plastic spring flat, it is breaking to be easy. If be 3 key mouses, may take apart intermediate any key to meet an urgent need. If is quality good pack famous-brand mouse , may weld , open micro-gap switch , wash contact carefully after, some last greases, pack can use.

Keyboard
Keyboard is in the process of using , the expression form of fault is varied, reason is also various. It has to contact bad fault , the mechanical fault that has the very button still has logic circuit fault , is empty to weld , holiday welds , weld and the faults such as metal hole oxidize, when repairing , will carry out analysis judgment according to different fault phenomenon , find out to produce fault reason , carry out corresponding repair.

Common fault one: Some keies on keyboard, is useless
Key does not be gotten up as cursor key after pressing
Come.

The fault " block key" with this kind of fault of keyboard, it is not only the old keyboard used very for a long time, have a few of have not used how long new keyboard go up, key fault also occurs the card of keyboard sometimes. Appearance the card of keyboard key phenomenon major from two following reasons cause: A kind of reason is key hat following insert column location deflection, make key hat can not spring with key body shell card after pressing have caused card key, this reason occurs the near keyboard in new keyboard or use. Another reason is very bad for button to become for a long time with the rear elasticity of return spring, shell fragment and according to rod friction force changes big, can not make button spring cause card key, this kind of reason many occur on the keyboard used for a long time. When keyboard appears to block key fault , may then press key hat group , to move according to rod. If according to rod bullet not get up or is lack of power, is caused by second kind reason, otherwise for the first kind of reason deliver. If cause because of the reason that key hat and key body shell block " block key " fault, may put a liner between key hat and key body , this liner may reach with some slightly hard plastic( if discard floppy disk overcoat), it size is equal to or omits to be larger than key body size , and it is opening one according to the location that rod passes through may make ammonium rod I love Xun the square hole that positive river passes through , cover it after when on rod, insert key hat; Prevent key hat and key body card to restore fault button with this liner; If since spring tiredness, the resistance of shell fragment changes big reason to cause to block key fault, now may special key body opens , stretching return spring a little make its recovery flexible; Take shell fragment recover key body. Through taking shell fragment, decreasing so makes fault button have gotten recovery according to the resistance from rod bullet.

Common fault 2:

Can not input if having only a certain key character,
Plate uses the coherent broken state of the resistance files measure contact of universal meter. If key presses throughout not Dao know , it is bad to explain that button spring flat is exhausted or contact , need to repair or change; If key presses contact knows to break is normal, explaining possibility is since empty weld , weld or golden bits hole oxidize delivers , may pursue part measure along printing line, finding out fault to carry out weight weld; If become invalid because of metal hole oxidize, it is clean to wash oxidize layer, then, weld jail again; If metal hole falls completely, and when causing broken road, add additionally to weld lead join.

Common fault 3: If have many not

Possibility is row line or trip line certain place broken road, or possibility is that logic door circuit produces fault. May carry out detection with the oscillograph of high frequency of 100 MHz now, find out fault device is empty to weld , restore then.

Common fault 4: The character

This kind of fault produces the phenomenon of short circuit on circuit board to cause , its expression is according to this key show that is the other characters of same one, right now, may carry out measure with universal meter or oscillograph , restore after determining fault point.

Common fault 5: Press a key to

This kind of phenomenon is caused by logic circuit fault. Choose first in a certain character, if without the certain trip of the key of carriage return, being certain to list , may produce other many character phenomenons; If containing one of the key of carriage return, will produce character to jump in disorder and can not enter systematic phenomenon finally, inspect logic circuit chip with oscillograph , change the new chip with model after finding out fault chip , remove fault

Printer
In office, the printer of ink jet is to use a kind of relatively general convenient equipment. It is the problem that user cares about that the printer of ink jet will often arise because of the reasons such as use, maintain and operating improperliness how some faults solve. When this we convenient will the summary of processing technique and the common fault in daily work come out , hope to help for all.

Common fault one: When printing , ink marks are rare, handwriting the handling that not identified , this fault majority is since printer long-term do not use or other reasons, cause ink transportation systematic obstacle or shower nozzle to block up.

The method of removing: If the obstruction of shower nozzle gets is not very severe, so direct execution printer goes up wash operation can. If still have no effect repeatedly after washing , may take ink box( the printer for non one body of ink box of spray nozzle, need to take spray nozzle, need to be but careful ) , put spray nozzle to soak a meeting in warm water , pay attention , do not also soak the part of circuit board in water surely, otherwise aftermath is unimaginable, inhale with blotting paper to touch some dripping after, pack wash some of spray nozzles again may.

Common fault 2: Change new ink box

Normal condition takes off , when ink has used " ink lets " lamp can just light. Change new ink box after, the lamp " ink is let " on printer face plate still lights , occur this kind of fault, one is possible ink box does not pack , another may be to take old ink box independently under barrier machine state , changes new ink box. After because change ink box again, printer will transport system for ink serve as ink, and this process will not go on under barrier machine state, make printer can not detection goes to the ink box on new installation. Is other, some printers for ink capacity measure use the built-in electronic counter of printer to go on is enumerated( especially when for color ink use statistics of quantity goes up ), when this counter reaches certain value, printer judgment ink is exhausted. When in ink box the process of changing , printer will carry out reset for its built-in electronic counter, so, confirm that have installed new ink box.

Solution method: Open power source , will print first move

Common fault 3:

What soft first obstruction is pointed at is that cause ink because of various reason when the viscidity on shower nozzle changes the broken line fault delivered. Normally, it is recoverable that using to pack ink box process repeatedly wash , but such method wastes ink too. The most simple method carries out shower nozzle using your empty ink box on hand wash. It is former to wash with empty ink box, will take out the remaining ink in ink box with needle pipe first as far as possible to happen , then join the more completely the more well, to wash liquid( accessory market sells ). Marking should go on in clean environment when washing liquid, the ink box that will be added to wash liquid according to the machine on operation with normal printer, press printer constantly wash key wash it. Print test using the remaining ink in ink box and the weak color that washes liquid mixture , change first-class ink box normally afterwards may use.

Common fault 4: Printer

It is more that printer washes pump mouth to make illness , it is also the one of major factor of causing head. Printer washes pump mouth to fight each other to print the protection of machine shower nozzle, take decision role. The pushcart of shower nozzle returns position, want from wash pump mouth to carry out weak bleed handling for shower nozzle, for shower nozzle carry out sealed protection. When printer installation new ink box or spray nozzle has broken line, machine next end take out to inhale pump will carry out bleed through it for shower nozzle, the working precision of this mouth is the more good the more. But when in reality use, its performance and air-tightness meeting because of time prolong , dust and ink when this mouth remain coagulum increase reduces. If use person, incorrect it often inspects or washes , it can make your printer shower nozzle unceasing, get some fault.

Maintain the method of this parts: Unload the upper cover of printer to put aside pushcart , suck in pure water with needle pipe to carry out wash for it , will wash fully for the tiny hole liner that inlays in mouth especially. When this will remind user especially , wash this parts, must can not use ethanol or carbinol wash it, so, can cause the tiny hole liner that inlays in this package to dissolve to warp. What will mention additionally is that the printer of ink jet the work of be far away from high temperature and dust as far as possible environment, only good working environmental talent guarantees that machine is for a long time normal to use.

Common fault 5: Detection

The printer meeting of ink jet in use since between the frequency of use prompt prolong print precision to change difference gradually. The printer shower nozzle of ink jet also has life-span. A general new shower nozzle is over to life-span since begining use, if do not make the what words of more smooth fault, also is 20-40 ink box use quantity life-span. If your printer has used very for a long time, now print precision to change difference , you may try with the method of changing ink box , if have changed some ink boxes, it is the same that it exports the result of printing , the shower nozzle of so your this printer will be changed. Have change after changing ink box, explanation possibility in you the ink box of use quality is more bad to not pack ink.

If printer is new, the result of printing can not make you satisfy , it is non-sharpness to often appear to print line segment , writing graph crooked, writing graph outside circle is fuzzy , print ink control synchronous precision difference, this explanation you possibility buies is the ink boxes of use or false ink box, is also to not pack product , should change immediately for it.

Common fault 6: Walk

The printer of ink jet walks the orbit of pushcart slides with the precise combination of two powder alloy copper covers and a round steel axles to be completed. Though walk pushcart goes up design installation has is a to contain the pad of asphalt felt with the lubricating oil on supplementary axle, but since we have dust everywhere in the environment of life, time one can make the ageing of lubricating oil of axle surface become invalid because of the damage of dust and the oxidize of air for a long time, now if continuity use printer, will cause pushcart to walk because of the friction force increase of axle and copper cover offset, turn till collision head causes can not use.

The method of solution is: Once arising this fault, should close printer power source immediately, use hand will do not return the pushcart of position to push to return parking position. Seek a little piece sponge or felt , put to soak full oil in the oil of sewing machine , clip with tweezers in the back and forth on main shaft to rub. Had better take apart main shaft , wash completely rear last oil, such effect is best.

Another kind of pushcart meets and discusses is delivered because device damages. There are a photoelectric sensor in the top of printer pushcart parking position, it is to offer to printer mainboard to print the important component of pushcart reset signal. This component if is big because of dust or damage, the pushcart meeting of printer meets first vehicle because of can't seek to return position signal, and cause to can not use , need to change device when geting this fault normally.

Display
The time that display uses has grown , various little illnesses will come one after another. Expert thinks that to solve these, little illness is simple actually , may find out the place of fault with a pair of eye.

Common fault one: Computer just start the picture flutter of display has to be very severe, sometimes, even linking icon and writing also see to not settle , but will return to normal after passing 1 or 2 minutes.

This kind of phenomenon occurs the weather in moist , is the display cause that is made moist inside. To solve this problem thoroughly, may use the dampproof sand in food package to use the rear cover of cotton thread that strings and then opens display , hang dampproof sand in the neck tail of picture tube near socket. So, in the weather in moist, will not also arise again " above illness ".

Common fault 2: Computer start after, display
This is the leakage of electricity of picture
Go up. Pull out this piece of circuit board carefully , and then weld socket , go to electronic shop to buy back a same socket , then, welding socket to return go to circuit board. Do not be anxious to pack circuit board to return now , will seek a little piece abrasive paper first, very carefully, it is clean to, with abrasive paper, polish the pin that bulges after the end of picture tube. Will especially notice the oxidize layer on pin, will not have a relapse completely very quickly if rubing. Packing circuit board to return succeed.

Common fault 3: Display screen goes up have

This kind of phenomenon probably is the difference
Force , may also try to change power source by
Come.

Common fault

This problem comparatively many show card arouse. If is new change show card, possibility is the quality of card is not good or not compatible , it is to have not installed correct driver to have again. If being old card , having added to show store , possible add recently enter show store and original show to store model parameter not one delivers.

Common fault

If is to show to block damage or the reasons such as display broken line cause no signal delivers display, the indicator light of display can twinkle continually to point out , have not taken over signal. If set up resolution ratio too high , the biggest resolution ratio that exceeds display can also arise dark screen , values person destruction display, but current display has to protect function , pawning resolution ratio to surpass to set can protect voluntarily when worthing. Additionally, hardware conflict can also arouse dark screen.
