What happens when the computer crashes?

In the computer failure phenomenon, the panic is a common fault, but also difficult to find the cause of one of the failures. According to the situation when the computer crash can be divided into four categories:

① during boot up: When you start your computer, you can only hear the hard drive self-test and not see the screen, or simply beep at post but the computer does not work, or when the post error prompts, etc.

② occurs when you start the computer operating system: The screen displays the computer self-test, but when the operating system is mounted, the computer crashes;

③ A panic occurs during the use of some applications: the computer is always running well and only crashes when executing some applications;

④ exits the operating system when the panic occurs: is in the exit WinXP and other systems when the panic. By the dry in the "panic" state can not use software or tools to diagnose the system, thus increasing the difficulty of troubleshooting. The general performance of the crash are: The system can not start, display a black screen, display "solidification", keyboard can not be entered, the software operation abnormal interruption.

in hardware, the culprit is the recent computer DIY industry popular "overclocking" one-let the CPU work in the rated operating frequency other than the clock frequency, the CPU is in excess working state, the crash is not surprising; second, one reason is a hardware overheating, or a hardware resource conflict. There are, of course, some other hardware reasons.

on the software side, the crash caused by software causes is almost the majority of computers (except for overclocking computers). Here is a brief look at the failure of the general inspection processing methods.

1, to troubleshoot virus infection caused by the panic phenomenon.

Use a non-toxic clean system disk to boot the system, and then run kill,av95, scan, and other anti-virus software to check the latest version of the hard drive, to ensure that the computer security, to eliminate the virus caused by the crash phenomenon.

In addition, if the virus caused the crash after the anti-virus, this is mostly because of viruses destroyed system files, applications and key data files, or anti-virus software in the elimination of viruses at the same time the normal files were mistakenly manipulated, the structure of the normal file damage. If you encounter such problems, you can only reload the system or software that is damaged (that is, the runtime causes the panic).

2, software installation, configuration problems caused by the crash analysis and elimination.

First, if the crash occurs during software installation, some of the system configuration may conflict with the software that was installed. These configurations include system BIOS settings, CONFIG. SYS and Autoexec.bat settings, WIN. INI, SYSTEM. INI settings and settings for some hardware drivers and memory-resident programs.

You can try to modify theDescribes the settings item. The BIOS can be set to its default settings, such as load SETUP default and load BIOS default, and for Config.sys and Autoexec.bat, you can skip the system configuration file at startup and F5 by F8, and modify it incrementally CONFIG. The configuration in SYS and Autoexec.bat (especially in EMM386 about EMS, XMS configuration) to determine where hardware and setup are in conflict, some hardware drivers and memory-resident programs can avoid conflicts by not loading them.

Second, if a panic occurs after the software is installed, the installed program conflicts with the system. The general practice is to restore the system before the installation of the various configuration, and then analyze the installation of new installed in the part of the use of resources and possible conflicts, step-by-Step troubleshooting reasons. Deleting a new installer is also one of the ways to resolve conflicts.

3, the system startup process of the panic phenomenon to analyze.

System startup process of the panic includes two cases:

A fatal panic, that is, the system self-test process has not completed the crash, the general system does not give a hint. This can be based on a list of fatal errors at post, combined with other methods to further analyze the cause of the failure.

Two is a non-fatal panic, in the self-test process or after the completion of the self-test, but the system gives the voice, text and other prompts information. Can be checked according to the non-fatal error code table at post and the error code table corresponding to the whistle sound at post. The sound of the siren in the post is the case listed in the error code table that focuses on the parts that may be faulty, but cannot ignore the inspection of the related parts, Because quite a few of the failures are not caused directly by the parts indicated by the message, they are often caused by the related part failure.

4, due to the use of improper maintenance caused by the crash analysis and elimination.

A computer may be used or maintained incorrectly for a period of time to cause a panic, especially after a long time without using a computer. The causes are as follows:

One is to accumulate dust caused the system to panic: dust is the enemy of the computer. Too much dust attached to the surface of the CPU, chips, and fans will cause these components to dissipate heat, and the dust on the printed circuit board often leads to short circuits in damp environments. Both of these situations can cause a panic.

You can use a brush to sweep the dust away, or use a cotton swab to clean the dust-accumulating elements with water-free alcohol. Be careful not to leave the hair brush and cotton swab on the circuit board and components to become a new source of panic failure.
