Explain the causes and preventive methods of the system crash

Today's computers are nearing universal popularity, and it provides great convenience for people to work and study. However, the computer's "dead" has become a common computer user. Unable to solve the troubles that can't be solved. Whenever the computer is turned on, when the operating system is booted, or when some applications are used, or when the operating system is being prepared to exit, "dead" is a "beast" that can be rushed at any time. So, what can we do to avoid the trouble of the computer & ldquo; crash? Below, the author is divided into several points according to the reasons and prevention methods that lead to "dead", I hope that the following articles can help some friends who encounter such problems.

First, the cause of the computer "dead"

1. "Hardware" caused by improper BIOS settings. Each hardware has its own default or specific working environment. It cannot be set beyond its working privileges. Otherwise, the hardware will not meet this requirement. Crash. For example, a memory stick can only support DDR 266, but in the BIOS settings it is set to DDR 333 specifications, this will crash because the hardware does not meet the requirements, if it can be normal in a short time In the work, electronic components will gradually age with the increase of the use time, and the quality problems will also lead to the frequent "dead" of the computer.

2. "hardware" caused by hardware or software conflicts "

computer hardware conflicts "dead" is mainly caused by conflicts in interrupt settings, when hardware conflicts occur, although each hardware is barely Can coexist in the system, but can not work at the same time, such as when you can access the Internet, you can not listen to music and so on. Over time, interrupted conflicts will occur frequently, and eventually the system will be overwhelmed, resulting in "dead".

Again, this is the case with software. Since different software companies develop more and more software, and these softwares are not completely familiar and compatible with each other during the development process, when running these software together, it is easy for everyone to happen. A conflict occurs when the same DLL or the same physical address is called at the same time. At this time, the computer system caused the system to be disordered due to the fact that it did not know which request to prioritize, causing the computer to "crash".

3. Hardware quality and failure caused by "dead" &

Because some small brands of computer hardware products are often put on the market without a qualified inspection program, many of them have quality However, the hardware products of Guan are very concealed under the circumstance of good quality computer hardware, which is not easy for ordinary people to see. As far as these hardware products are concerned, the cause of the computer often "dead" is very directly related to them. In addition, some hardware failures are caused by the longevity of the use. In general, the life of components such as memory modules, CPUs, and hard disks is difficult to guarantee after more than three years, and there are also many hidden "dead" problems.

4. When the computer system is running out of the wrong program or code, the internal system of the system will form a "dead" cycle, which is very limited. The system resources will be put into endless repetitive operations. When the operation ends up, the computer will be exhausted due to the excessive use of the computer. Another point is that a large number of programs are running in the computer operating system, resulting in insufficient system memory resources resulting in "dead".

5. The system file is mainly caused by files that are critically supported when the computer system is started or running. If they are missing, the entire computer system will not function properly. The operation, of course, "dead" is inevitable. There are many reasons why system files are corrupted. The invasion of viruses and hackers is the main reason. In addition, the primary user may have this effect due to incorrect operation and deletion of system files.

6. "The crash caused by poor internal heat dissipation in the computer" is due to the fact that the main component of the electronic components inside the computer is silicon (this is an element whose working state is greatly affected by temperature). When the computer is working, the temperature of the electronic components will increase accordingly, and electron migration will occur on the surface, which will change the current working state, causing the computer to suddenly "dead" in the work.

7. The failure of the novice user caused by the "failure"

For the novice user, some wrong operations during the use of the computer will also cause the system to "dead". For example, hot-plugging hardware, vibrating computers during operation, arbitrarily deleting files, or installing software that exceeds the basic hardware setting standards can cause "dead".

8. Others caused by "dead"

In addition to the reasons described by the author above, there are many strange reasons that may cause the system to "crash". For example, voltage fluctuations are too large, optical drive read capacity is reduced, floppy disk quality is poor, viruses or hacking programs are destroyed. In short, the reasons for the computer crash are many.

From the above points, the computer "dead" is not a good thing for the average user, but it is not inevitable, as long as the user follows the normal computer operation, I believe that "dead" The chances are reduced to a minimum. Below, the author summarizes some of the experiences summarized on the cause of the computer crash.

Second, the computer "crash" prevention

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

2. Always check the contact of computer accessories. Running under the condition of bad contact of the board will cause the system to crash, so when replacing the computer accessories, be sure to make the board fully contact with the motherboard.

3. Clean the chassis regularly. Too much dust can cause poor contact between the boards, causing the system to crash during operation. Therefore, the chassis should be cleaned at all times, so do not allow too much dust to accumulate in the chassis.

4. Stick to the virus. For discs or floppy disks of unknown origin, do not use them easily. For attachments in emails, check with anti-virus software before opening.

5. Shut down in the correct sequence of operations. Do not turn off the power before the application software finishes running normally. Otherwise, the system files may be damaged or lost, causing a crash during startup or operation.

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

7. Don't overdo it. Drivers of various hardware do not have to be updated at any time, because the drivers that are developed often have bugs inside, which will cause damage to the system and cause the system to crash. The latest is not necessarily the best.

8. When uninstalling the software, use the built-in anti-installer or the installation/uninstallation method in Windows. Do not delete the program folder directly, because some files may be shared by other programs. Once these shared files are deleted, the application software will be unavailable. And crash.

9. When setting up the hardware device, it is best to check for the presence or absence of an interrupt (IRQ). Do not let other devices use the interrupt number to avoid an interrupt conflict and cause the system to freeze.

10. When surfing the Internet, don't open too many browser windows, otherwise it will lead to insufficient system resources and cause the system to crash.

11. If your machine's memory is not very large, don't run programs that take up a lot of memory, such as Photoshop, otherwise it will crash when running.

12. For system files or important files, it is best to use implicit attributes so that they do not delete these files due to incorrect operation, causing the system to crash.

13. When modifying the hard disk master boot record, it is best to save the original record first to prevent the original boot record from being restored due to the modification failure.

14. CPU, graphics card and other accessories generally do not overclock, if you really need to super, pay attention to the temperature of the card after overclocking, CPU, graphics card and other long-term work under abnormal frequency and temperature will automatically restart or crash, the heavy burned CPU, graphics card, Motherboard.
