The reason and solution to the computer's unexplained crash

1. Installing too many operating systems on the same hard drive can cause the system to panic.

2.CPU, display cards and other accessories do not overclocking too high, to pay attention to temperature, otherwise, in the start-up or run will inexplicably restart or panic.

3. In the replacement of computer accessories, be sure to plug in, because the accessories contact bad will cause system panic. The

4.BIOS setting is appropriate, although it is recommended to set the BIOS to optimal, but the so-called optimal is not the best, sometimes the optimal setting will cause startup or run panic.

5. It is best to be equipped with a power supply to avoid voltage instability caused by panic.

6. If there is a condition, install a UPS, so that the computer will not cause a crash after power failure.

7. The floppy disk and CD-ROM of dubious origin, do not use easily, the software attached to e-mail, to use KV300, rising and other anti-virus software to check and then use, so as to avoid infection after the virus, is the system panic.

8. Do not turn off the power when the application is not working properly, or it will cause the system files to be corrupted or lost, causing the automatic startup or panic in operation. This is very important for systems such as WINDOWS98/2000/NT.

9. In the installation application software, if the prompt dialog box "Overwrite Files", it is best to choose not to overwrite. Because the current system files are usually the best, it is not possible to overwrite the files based on the time sequence (unless you care about the time of the file).

10. Do not delete the shared files when uninstalling the software, because some shared files may be used by the system or other programs, and once deleted, they can cause the application to fail to start and panic, or the system run panic.
11. When setting up a hardware device, it is best to check for a reserved interrupt number (IRQ), do not let other devices use the interrupt number, or cause IRQ conflicts, causing the system to panic.

12. When loading some software, should pay attention to the order, because some software programming is not standardized, in the operation is not ranked first, but to put in the last run, so that will not cause confusion in system management.

13. When running a large application (such as Office 2000), do not exit the previously running program in the running state, or it will cause the entire WINDOWS98 system to crash.

14. In the case of small memory (such as 4MB-16MB), it is best not to run memory-intensive applications, otherwise it is prone to panic at run time. It is recommended that you save the files that are currently in use when you run these programs.

15. For system files or important files, it is best to use suppressed properties so that they are not deleted or overwritten by mistake.

16. When you modify the master boot record for a hard disk, it is best to save the original record to prevent the original hard disk master boot record from being restored because of a modification failure.

17. It is best to use the beta version of the software sparingly, because the beta is not stable enough in some way and the system will not start after use.

18. Try not to run 16-bit applications in WINDOWS95/98 because 16-bit applications conflict with 32-bit applications in Windows, causing a panic or failure to start.

19. Before upgrading the BIOS, you should determine which BIOS version is upgraded, and you should first save the previous version so that the system does not boot because of an upgrade error.

20. Try not to use pirated software, because these software hidden a large number of viruses, once executed, will automatically modify your system, so that the system in the operation of the panic.

21. In the case, there may be a large amount of dust, dust contact with the circuit of accessories, will make the system unstable or panic.

22. Do not run a large application after defragmenting the disk, or cause a panic.

23. Do not run other applications to prevent the system from crashing while checking the hard drive with antivirus software.

24. When surfing the Internet, do not open too many browsing windows at once, resulting in insufficient resources, causing panic.

25. When you turn off your computer, do not use the power button directly in the chassis, because using the power button directly causes the file to be lost, so that the next time it does not start normally, causing the system to panic.

to often crash friends, please try the above methods, I believe that we will have a certain help, and sometimes to specific circumstances to take different countermeasures, must not apply mechanically Oh!

Analysis of common causes of crash

Everyone knows that the crash is one of the most common problems you use in the computer process, and the cause of the crash is confusing, unpredictable, and even once let you .... In the previous DOS era, the cause of the crash is usually virus-oriented, of course, there are other reasons, such as the application of software settings, etc., so the resolution of the crash also has a certain mode, specifically is the first anti-virus, check the hard disk space is not enough, Then check the Autoexec.bat and Config.sys files for error commands, if the problem is not resolved, you can check the hardware, that's all. But now is different, now is the Windows age, the cause of the crash is ever-changing, so it is quite tricky to deal with. Anyway, the resolution of the crash are first soft and hard, the software is of course the first anti-virus, then some applications, drivers and so on installation, you also do not forget the Registry Editor and some of the CMOS settings Yo, and finally teach you a trick is the most effective way to put the hard disk out (a joke). The main hardware is the heat dissipation problem, now the machine run fast, of course, the resulting heat is more, and then use the most effective hardware troubleshooting Method-replacement method, find the real killer. Said so much or specifically to talk about the crash, from the computer startup, operation and shutdown phase of the crash phenomenon for a simple analysis.

Panic during startup
    to analyze how the computer crashes when it starts, you must first understand the order in which the computer system is started, and then analyze whether it is caused by a software problem or a hardware failure. So here it is necessary to briefly introduce the computer system's starting sequence: Turn on the computer power → detect video card → detect memory → perform bios→ detect other devices (CPU, hard disk, etc.) → execute operating system (OS) initialization files. The operating system startup process is more complex, first of all ROM (read-only memory) in the bootstrap loader program and the self-diagnosis program to the RAM (random memory), with the bootstrap loader running, The system files for the operating system are also loaded into RAM, and then the Io.sys and Msdos.sys system files are executed, and the "Starting Windows 98 ..." screen appears on the computer monitor. Finally, System.ini and Win.ini are initialized to read the registry files. If there is no problem, it will be successful to start the computer system. Here is an introduction to the process of the crash occurred.
    After the boot system does not have any response: if the power supply does not start to see whether the power cord is not connected to good, even the power cord without any improvement, the fault may be a power supply problem, replace the power supply try.
The computer monitor does not respond after powering up, and accompanied by 1 long 2 short alarm sound after the crash: The first exclusion is the monitor failure, because even if the monitor has a fault is not cause computer crashes, this situation is mostly because the display card is not plugged in place or loose, open the chassis to reinstall the display card, Or try a different slot, so the problem can be solved.
    Monitor has a short display adapter information, and with 1 long 1 short alarm sound after the panic: since the display adapter information, the display adapter is not a problem, this situation is often a memory failure, The solution is to open the chassis to reinstall the memory bar try, if not, if not, change a piece of memory to try, of course, you must carefully look at the expansion slot is not intact, this will certainly be able to eliminate this fault.
    crash after BIOS upgrade failed: Locate the computer on the same model BIOS board, back up the BIOS program on this computer, and refresh it with the BIOS refresh program, provided the BIOS is able to refresh.
Incorrect CMOS settings caused by the panic: This fault is very much, this is only a common example, such as the hard drive parameter settings or improper mode settings caused the computer can not start, withinImproper setting of stored parameters, such as the memory without ECC function to set it to have ECC function, so often because of memory errors caused by computer crashes, and so many examples, users only need to modify the settings to come.
    computer after overclocking startup computer panic: Now Overclocking is a very fashionable topic for the vast number of computer users, and occasionally overclocking the computer, especially now many motherboard manufacturers will be overclocking in the CMOS, so DIY don't mention how happy , because overclocking is more convenient and quick, but does overclocking have the limit? It is not known, if it is overclocking after restarting the computer in the process of panic, it is your overclocking too high, need to lower some.
Incorrect deletion or error of     system files causes the computer to fail to start and render panic: Because Windows startup requires Command.com, Io.sys, Msdos.sys and Drvspace.bin four files, if these files are damaged or mistakenly deleted, even in the CMOS hardware settings are correct, it is no use, the system will not be able to start, the solution to the problem only with a floppy disk to boot the computer (of course, the system version of the same system disk), and then type SYS c: you can.
    initialization files are corrupted causing the computer to fail to start and render panic: Windows startup requires reading System.ini, Win.ini, and registry files (User.dat, System.dat), if there are Config.sys and Autoexec.bat files are also to be read, as long as there are error messages in these files can occur panic, especially System.ini, Win.ini, User.dat and System.dat These four files are particularly important, as long as there is a bit of error system will not start, for this I strongly recommend that users usually have to back up the four files.

Panic during run
    runtime panic refers to the panic that occurs when we use Windows, which means that you run some applications under Windows operating platform without complaining about the crash. Some of this is a conflict between the application and the operating system, some are bugs in the application itself, and so on, the following on the operation of the crash to explain.
    crashes when running certain applications: The reason for this failure is roughly three possible, one is that the application is infected with the virus, and there are bugs in the application itself, and there is some conflict between the application and the operating system.
The panic caused by a shortage of     resources: too many open applications during use, consuming a large amount of system resources, resulting in insufficient resources during use, so it is best to open less software that is not relevant to this application when using larger applications.
    hard disk left too little space or too much fragmentation caused the panic: if the hard disk space is too small, because some applications run a large amount of memory, which requires virtual memory, and virtual memory is given by the hard disk, So the hard disk to have enough space to meet the needs of virtual memory, but also is that we have to develop a regular time to organize the hard drive habit.
    Some files are overwritten to run some application crashes: When installing new applications, there are some file coverage prompts, I suggest you should not overwrite any file operation, otherwise it may cause the operation of some applications of the crash (prevention).
    Some files are deleted to run some application freezes: when we uninstall some of the applications will often appear on the deletion of certain files prompts, if you are not particularly aware of the file and other documents are not related, it is best not to delete it, Failure to run some applications may result in the loss of some files, or even the horrors of the entire system crash (prevention).
The mouse keyboard does not respond after the     program is run: The application crashes after running, indicating that the application is not running normally, and that the system resources are occupied and the operating system is not clear about this. The end application is enforced only by holding down the CTRL, ALT, and Del Keys at the same time, ending the task.
Setting the power-saving function causes the display to be frequently black-screen panic: it is generally due to a short period of time in the BIOS, or the time set in the screen saver.
 &NBsp;  hardware overclocking caused the operation of the panic: overclocking after the computer can be started, indicating that overclocking is successful, why the operation will appear panic? is generally due to overclocking hardware produced a lot of heat can not be distributed in a timely manner caused by the crash, so often we overclocking at the same time also to the cooling device for reasonable improvement.
Hardware: Computer hardware configuration is too low, memory speed mismatch (crash: Mouse can move, click No response), interrupt settings caused by the conflict between the hardware, a variety of drivers do not match, etc. can also cause in the operation of the phenomenon of panic. The

Panic when shutting down the system
    The panic that occurs when exiting the operating system refers to the panic that occurs when exiting the Windows system or returning to DOS. If Windows does not shut down completely, the data in the disk buffer will be written to the hard disk and then into a dead loop, and the system cannot be shut down unless the user restarts the system. The reason for this may be related to operating system settings and some improper driver settings, when Windows generally shuts down drivers that are in use when exiting the system or returning to DOS, and these drivers will write a data-back operation based on the circumstances, but if the driver is improperly set, The driver cannot find the device, so it keeps searching the device, thus creating a fake panic.

In short, a lot of reasons for the crash, anyway, we deal with the general method of the crash is the first soft after the hard, that is, consider the application software after the hardware failure, focus should be placed on the software, is mainly in the application of installation settings and some driver installation settings to find out why. Finally, for hardware reasons, general hardware reasons can be found either through device management in the system setup or from System information in the Windows operating system attachment.

Case study: The computer I met was inexplicably dead. Failure resolution

Bought a computer in the early years, with always very good, usually clean up the system garbage, sweep a sweep has been secretly installed some rogue software, there is anti-virus software, firewall normal operation of everything without worry. As for the hardware of some dust cleaning is also half a year, Plug and draw line is also more often, so all the normal operation. But it's been a bit of a problem for almost a year,

       A, symptom
      
      The first stage: only the system reaction slows down, but also can be used for a period of time;
      Phase II: Occasional Crashes, Phenomenon such as: usually run a software or run multiple software at the same time is normal, but now will be stuck, slow or even panic.
      Phase III: More serious, occasionally boot into the desktop without any operation will crash, more frequent failures. or before entering the system is to prompt a disk read error occurred errors (specific I also remember not very clear). And sometimes it can be used normally, the phenomenon is very random.

      II, troubleshooting

      The first phase of occurrence after these circumstances I took the cleaning system garbage, Clean up unwanted software, files, and the memory and boot run files for virus killing. Later look at some of the online users of the article to take the defragmentation disk fragments, temporarily eased, not a few days fault and out. Later bite teeth-reload system, installed a few times, can not solve the problem.

      has to carefully study the occasional a disk read error occurred, which can be guessed by the literal meaning of a part of the hard disk that is causing the exception. The hard drive has to be removed after it is determined that it cannot be solved (I removed the hard drive directly because of the chassis problem). Fortunately, my Computer store boss good intentions do not care, if the matter is not necessarily willing to help me repair it, to go to the computer store, the next day to go, the store said nothing wrong, told me to move the chassis, had to move. Because the fault is only happened, so check in the shop for a long time did not find out, the store was asked will be hard data cable (forgot to say my computer hard disk interface is SATA) problem? But the maintenance staff don't quite feel that they think the hard drive data cable doesn'tEasy to bad, then there is no way, I changed the root data line let me first use, and so there are problems to test again. Haha, did not think that a use of the now is no problem, so you can be sure that the fault is due to the hard drive data cable causes.

      Write this article just to provide a reference for friends who have the same fault, the computer fault is strange, sometimes the fault is similar but there are other reasons for this failure is also possible. I wish you a smooth solution to your computer malfunction!
