The computer suddenly can't open the machine what's going on

It may be too hot, or a faulty circuit, or a power problem.

① boot during the crash: in the start of the computer, only hear the hard drive self-test sound and can not see the screen display, or simply in the post beep sound but the computer does not work, or in the post error prompts;

② in the start of the computer operating system panic occurs: Screen display computer self-test passed, but in the installation of the operating system, the computer appears to panic;

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

④ exits the operating system when the panic occurs: is in the exit Win98 and other systems or return to the DOS state 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. There are probably tens of thousands of reasons for the crash, but only two aspects: one is caused by computer hardware, one is the software design is not perfect or with the system and other running programs conflict. In the hardware, the culprit is recently in the computer DIY industry popular "overclocking" A-let the CPU work in the rated operating frequency of the clock, the CPU in excess of working state, there is no strange panic; second, one reason is that some hardware is overheating, or a hardware resource conflict. There are, of course, some other hardware reasons. On the software side, the crash caused by software is almost the majority of computers (except for overclocking computers). The 16-bit and 32-bit hybrid kernel mode is used in the Windows9x series, so the security is low, and the crash due to a program memory conflict is something that happens frequently. Here is a brief introduction to the general method of inspection and treatment after the crash

First, the elimination of the system "fake" crash phenomenon

1. First of all, to eliminate the power problems caused by the "false" crash phenomenon. Should check whether the computer power is plugged in, the power outlet is contacted well, host, monitor and printer, scanner, external modem, speakers and other major external power equipment power plug is reliably plugged into the power outlets, the above parts of the power switch is in the state of open (on).

2. Check the data between the parts of the computer, control whether the connection is correct and reliable, whether there is loosening between the plugs. In particular, the host and the display of data cable bad often caused by "black screen" false panic phenomenon.

Second, the elimination of virus infection caused by the crash with non-toxic Clean system disk boot system, and then run kill,av95, scan, such as the latest version of anti-virus software to check the hard disk, to ensure computer security, to eliminate the virus caused by the crash phenomenon. In addition, if the anti-virus caused by the crash, this is mostly because the virus destroyed the 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 operated, 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).

Third, the elimination of software installation, configuration problems caused by the crash phenomenon

1. If the crash occurs during the software installation process, it may be a conflict between some of the system's configuration and the software that is 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 the settings above. The BIOS can take its default settings, such as "load SETUP default" and "Load BIOS default"; For Config.sys and Autoexec.bat, you can either skip the system configuration file at startup, or press F8 for step-by-Step execution and modify the configuration in Config.sys and Autoexec.bat individually (especially in the EMM386 configuration of EMS, XMS To determine where the hardware is in conflict with the installer, some hardware drivers and memory-resident programs can avoid conflicts by not loading them.

2. If the software has been installed after the crash, it is a good installation of the program and the system conflict. 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.

Four, according to the system start-up process of the crash phenomenon to analyze the system startup process of the crash, including two cases: 1. 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.

2. 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 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.

V. To eliminate the panic caused by the use of improper maintenance computer after the use of a period of time may also be due to the use of improper maintenance caused by the panic, especially after a long time does not use the computer often appear such faults. There are several reasons for this:

1. Dust accumulation 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. The concrete treatment method may use the brush to sweep the dust away, or uses the cotton swab to dip the anhydrous alcohol to clean the dust accumulation element. 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.

2. Parts damp: Long time does not use the computer, will cause some components damp but not normal use. can use the low heat of hair dryer evenly to damp element "dry". Note that you must not heat the component part too long or the temperature is too high to avoid baking a bad component.

3. Board card, chip pin oxidation lead to bad contact: the board, chip out, with the eraser gently wipe the surface of the pin to remove oxides, reinsert the socket.

4. Board card, peripheral interface loosening cause panic: Carefully check the I/O slot plug is correct, the interface between the peripherals is good, cable connection is normal.
