<br> <br> 4. as a result of the use, maintenance, improper caused panic in analysis and troubleshooting. <br> <br> The computer is in use for some time because of improper use, maintenance, causing panic, especially .long time not to use when your computer is experiencing such a failure. The reasons caused by the following: <br> <br> One is the dust causes System lockup: dust is the enemy of the computer. Excessive dust attached to the CPU, .chipset, fans of surface can cause these adverse, circuit components thermal printing plate dust in a humid environment often cause a short circuit. The above two situations will cause panic. <br> <br> Specific treatment method can be used to brush the dust .sweep, or cotton swab soaked in alcohol cleaning dust components. Note do not put the brush and cotton wool, cotton, stay on board and components into a new panic fault source. <br> <br> The second is part damp: long time .not to use a computer can cause partial components damp cannot normally use. Free hair dryer of low heat retaining moisture uniformity on the symbol "baking". Note is not part of the heating element for too long or too hot to avoid baked bad symbols. .<br> <br> Third, the Board, chip PIN oxidation causes bad: boards, chip unplugged, gently wipe with an eraser to remove oxide on the surface of the PIN, back into the outlet. <br> <br> Fourth Board .card, peripheral interface loose lead to panic: double check the I / O slot docking is correct, the peripheral interface contact is good, the cable is connected correctly. <br> <br> 5, because the system configuration of panic caused by wrong .analysis of the phenomenon. <br> <br> System configuration and computer hardware device and the system BIOS, motherboard jumper switch settings are closely related, common panic failure causes are: <br> <br> (1) frequency settings improperly: such .failures are CPU clock speed jumper switch setting error, caused by a Remark of CPU BIOS settings does not match the actual situation, overclocked CPU or CPU performance bad panic. <br> <br> (2) improper memory parameters: such failures are memory .settings error and Remark memory caused by BIOS settings does not match the actual situation. <br> <br> (3) CACHE parameters are set incorrectly: such failures are mainly RemarkCACHE CHCHE settings error, causing the BIOS settings and the actual situation. < .br> <br> (4) CMOS parameter is broken: frequently modify CMOS parameter, or virus to CMOS parameters, can often lead to confusion and CMOS parameter is very difficult to restore. You can use the CMOS discharge method and use the system BIOS .default setting value reset CMOS parameter. CMOS discharge method can refer to your motherboard documentation. If a virus infection, reset CMOS parameter, you must disinfect the hard drive. <br> <br> 6, hardware, installation of panic caused by improper and .excluded. <br> <br> Hardware peripherals installation process neglect often lead to strange panic, but this phenomenon often in computer use for some time before gradually revealed, thus has a certain amount of confusion. <br> <br> (1) .components installed are not in place, docking loose, wired incorrectly caused panic, display card and I / 0 slot bad often causes display of panic error, such as "black", memory, CACHE and slot docking loose you often brings programs run in panic ., and even system cannot be started, other card and socket (receptacle) contact problems often cause panic. To exclude these fault, simply add the appropriate Board card, chip hand honk the tight, or from the socket (receptacle) disconnect the reinstall. .If you have spare socket (receptacle), or the parts for a socket (receptacle) installation to resolve contact problems. Incorrect cable connections may sometimes cause panic. <br> <br> (2) improper installation lead parts deformation, damage caused by .the calibre of panic is incorrect, inappropriate screw length often result in part mounting hole damaged screw contact to the internal circuitry caused short circuit parts causing panic, no specification of the motherboard, spare parts or improper installation steps often brings on chassis, motherboard, the .Board shape variations and thus squeeze the internal components lead to partial damage to the internal components of short circuit, so strange panic occurs. If only the computer part appearance deformation, can correct installation method and replace the specification parts to solve; if you have already .caused damage to the internal components, you can only replace the new parts. <br> <br> 7. hardware quality problems caused panic in analysis and troubleshooting. <br> <br> In General, computer products are large international manufacturers in accordance .with international standards in assembly line production, parts defective rate is very low. But the lure of profit made many illegal manufacturers on the computer standard parts has changed forever, changed channels, Relabel (Remark), shoddy even rejects and seconds as a genuine sale ., causing these "superlative" play of product performance, environment slightly unwell or use time is longer, it will frequently fails. Especially the CPU, memory, motherboards, and other core components and related products of poor quality is no reason to panic's main fault .source. Should focus on checking the following parts: <br> <br> (1) CPU. .CPU is impersonated most is extremely easy to cause panic. The CPU is Remark in low temperatures, short-time use, everything is normal, but as long as the continuous high temperature environment in a long time, its panic drawbacks are easily exposed. Use .Windows, 3DS, and so on CPU performance demanding software than DOS, simple software can better find CPU problem. If you need to confirm that you want to do this is to confirm that the failure to refer to the CPU clock speed jump statement is low .grade 1 and 2 will be using, such as reduced to 150, 166 133 or 120. If panic among significantly reduced or lost, you can determine the CPU. You can also useExchange method, replace the same model of normal CPU, if not panic .generally can be concluded that the issue of the CPU. Some users prefer to use the CPU overclocking for high speed performance, which is often causes the computer to crash. General CPU jumps back to the original frequency can be settled in a panic. <br .> <br> (2) memory stick. Memory stick is often made of hands and feet are: speed mark is changed, such as: 70ns is Remark as non-parity 60ns, posing as a non-parity memory, posing as EDO memory .EDO memory, poor memory stick memory stick as well. In the BIOS read and write to the memory of the appropriate increased time (eg from 60ns promoted to 70ns), if the panic away can determine that the problem is memory speed. If the quality .issues of memory itself, only the replacement of the memory stick to resolve. <br> <br> (3) the Board. General Board of failure are often among the first to consider however is to be determined at the end of the day. .In addition to the printing plate on the flight line, breakage and motherboard components were burnt, motherboard by extrusion, motherboard and chassis short circuit and so obvious phenomenon, the Board's own fault only confirmed all components on the motherboard correctly (to your Board, CPU ., memory, and other accessories to good use normal on the motherboard, and others use normal card, device into your motherboard will not run properly) in order to determine whether a motherboard failure, if you replace a good motherboard with model still exists in a .panic, it is likely that this Board is not compatible with one of the parts. Either replace the compatibility of other models of the motherboard, or can only be used to test various seated method in turn card, chip, identify incompatible parts replacement. < .br> <br> (4) power supplies, fans, chassis, etc. Inferior power supply, power cable failure, power plug loose, supply voltage instability are caused by unknown cause panic. CPU fan, power supply fan is not working properly, .the fan power shortage is caused by the CPU and the box "Thermogenesis payer component cooling-performing thus cause panic. <br> <br> 8. system bland excluded. <br> <br> System lockup failure usually manifested as black screen ( .that is, the monitor screen, no show), such a failure and the monitor, display card relationship is a close, and the system motherboard, CPU, CACHE, memory, power supplies, and other parts of the fault can lead to a black .screen. System black screen of death crash of general inspection methods are as follows: <br> <br> (1) to exclude false black: check the monitor power plug is plugged in, the power switch is turned on, the monitor and display .adapter on the host's data cable is connected properly, connect, shaking his head is loose, it is because of these factors caused a black screen. In addition, you should move the mouse or press the keyboard and see if the screen back to normal. .Because black screen may set the power saving mode (available in the BIOS settings to view and modify) and robustness. <br> <br> (2) at a black screen at the same time the rest of the system is working properly, such .as: Startup soft / hard disk drive with a keyboard key is passed, whether there is a reaction, and so on. You can exchange method used a good monitor add-in host test, if you just display a black screen and the other part ., is only a problem with the monitor, which still is a robustness. <br> <br> (3) black screen in the system during the post, see step 4. <br> <br> (4) black screen in the .display driver installation or set the display mode, apparently chose to display the system cannot support mode, select one of the more basic display. Such as: Windows settings display mode is black or the video, you should run in DOS directory on Windows Setup. .exe program select the standard VGA display. <br> <br> (5) check the graphics card and the motherboard I / O socket contacts are good, reliable, and if necessary, change the I / O slot Insert display cards a try. .<br> <br> (6) change a confirmed the performance with the models displayed card plugged into the host is restarted, if black screen of death in the Elimination of the display card. <br> <br> (7) for a .confirmed the good performance of the other models show the card into the host is restarted, if black screen of death in the Elimination of the display card is not compatible with the host, consider replacing the graphics card or motherboard. <br> <br> .(8) check if error is set at the heart of the system components, such as the frequency of the CPU, memory, read-write time, CACHE refresh, the motherboard bus speed, which can cause a black screen of death. <br .> <br> (9) check host internal parts wiring is correct, there are some special wiring error causes the black screen of death. <br> <br> <br> <br> <br> <br>.
