What causes the computer system to crash?

Today's computer is close to the full extent of popularity, to provide people with great convenience in work and study, but the computer's "death" for ordinary computer users, but became a solution not open, earn not take off the trouble. Whenever the computer is powered on, or when the operating system is started, or when some applications are in use, or if you are preparing to exit the operating system, the "beast" of the "dead" is at any time likely to pounce. The following is a breakdown of the causes of "death" and prevention methods are divided into several.

Causes the computer to "crash":

1.BIOS improper settings caused by the "dead", each hardware has its own default or specific work environment, can not casually beyond the work permissions to set, otherwise it will be due to the hardware can not achieve this requirement and the crash. For example: A memory bar can only support to DDR 266, but in the BIOS setup is set to the DDR 333 specification, this will be due to the hardware does not reach the requirements of the crash, if you can work in a short time, the electronic components will increase with the use of time and gradually aging, The resulting quality problems can also cause the computer to "crash" frequently.

2. Hardware or software conflicts caused by the "dead", the computer hardware conflict "Panic" is mainly caused by the conflict of the interrupt settings, when a hardware conflict occurs, although the hardware can barely in the system {XX}, but not at the same time to work, such as the ability to surf the internet can not listen to music and so on. A long time, the interruption of the conflict will occur frequently, and eventually will lead to the system overwhelmed, resulting in a "crash."

Similarly, this is the case with software. Because of the growing number of software developed by different software companies, and the fact that these software are not fully familiar with each other in the process of development, it is very easy to have the same DLL or the same physical address at the same time when we run the software together. At this time the computer system is not aware of the priority to deal with which request, resulting in a system disorder and caused the machine to "crash."

3. Hardware quality and fault caused by the "death", due to the current small brands of computer hardware products are often not passed the qualified inspection procedures on the market, among them, there are many quality of hardware products in good quality intact computer hardware shrouded is very hidden, ordinary people are not easy to see out. As far as these hardware products are concerned, the reason why computers often "crash" has a very direct relationship with themselves. In addition, some hardware failures are due to the use of a long time to produce. In general, memory, CPU and hard disk components such as the life of more than three years after the very difficult to guarantee, which will also create a lot of hidden "panic" problem.

4. The "death" caused by the exhaustion of the computer system, when the computer system executes the wrong program or code, it will make the internal system "dead" cycle phenomenon, the original very limited system resources will be put into the endless repetition, when computing to the end because the computer is too large to run out of resources caused " Crash ". Another point is that in the computer operating system running a large number of programs, so that the system memory resources are not enough to cause "the crash."

5. System files are corrupted caused by the "crash", system files are mainly refers to the computer system start or run when the key supporting files, if missing, the entire computer system will not function normally, of course, "panic" is inevitable. There are many reasons why system files are corrupted, and the intrusion of viruses and hacking programs is the main reason. In addition, the primary user due to the wrong operation, the removal of system files will also cause this effect.

6. The "crash" caused by poor heat dissipation in the computer, because the main component of the electronic components inside the computer is silicon (this is a working state is affected by temperature is very large element). When the computer is working, the temperature of electronic components will increase, the surface of the electronic migration phenomenon, so as to change the current state of work, resulting in the computer in the work of a sudden "crash."

7. The "Crash" caused by the error operation of the novice user, for the novice user, in the process of using the computer, some wrong operation will also cause the system "crash". For example, hot-swappable hardware, shaking a computer during operation, deleting files at will, or installing software that exceeds basic hardware setup standards can cause "panic".

8. Other causes of "death", the above reasons, there are many strange reasons may lead to the system "crash." For example, the voltage fluctuation is too large, the optical drive reading capacity decline, floppy disk quality, virus or hacker program destruction and so on. In short, the cause of computer crashes is manifold.

From the above points can be seen, the computer "crash" is not a good thing for the general user, but it is not inevitable, as long as the user in accordance with the normal computer operation, I believe that the "death" probability will be reduced to the least.

Second, the prevention of computer "crash"

1. Ensure the correct BIOS settings. The BIOS settings must be appropriate, and the wrong BIOS settings will cause you to crash while running Windows.

2. Always check the contact of computer accessories. In the case of bad board contact will cause the system to crash, so in the replacement of computer accessories, it is necessary to make the board and the motherboard full contact.

3. Clean the chassis regularly. Too much dust will make the card contact between the bad, causing the system to crash in operation, so the chassis should be clean at any time, do not let too much dust accumulation in the chassis.

4. Insist on serious virus killing. On the unknown CD-ROM or floppy disk, not easy to use, the attachment in the mail, you must first check with antivirus software before opening.

5. Turn off the machine in the correct order of operation. Do not turn off the power until the application has finished running properly, or it will cause the system file to be corrupted or lost, causing it to crash during startup or operation.

6. Avoid multitasking at the same time. Do not run other software while performing disk grooming or checking the hard disk with anti-virus software, otherwise it will cause the crash.

7. Do not be overly novelty. All kinds of hardware drivers do not have to be updated at any time, because the driver is often developed inside the bug, will cause damage to the system, causing the system to panic, the latest is not necessarily the best.

8. When uninstalling the software, use the self-contained anti-installation program or Windows Install/uninstall method, do not directly remove the program folder, because some files may be shared by other programs, once deleted these shared files, will cause the application software can not be used and panic.

9. When setting up a hardware device, it is best to check for non-reserved Interrupts (IRQ), do not allow other devices to use the interrupt number, so as not to cause interrupt conflicts, causing the system to panic.

10. When surfing the Internet, do not open too many browser windows, otherwise it will lead to insufficient system resources, causing the system to panic.

11. If your machine memory is not very large, do not run a large memory-intensive program, such as Photoshop, or the runtime is prone to panic.

12. For system files or important files, it is best to use the implied attribute so that the file is not deleted due to an error operation, causing the system to panic.

13. When modifying the hard drive master boot record, it is best to save the original record and prevent the original boot record from being restored because of the modification failure.

14.CPU, graphics and other accessories generally do not overclock, if you do need ultra, to pay attention to overclocking after the board temperature, CPU, video card and other long-term abnormal frequency and temperature work light automatically restart or panic, heavy burned CPU, graphics card, motherboard.
