Hello, everyone. Lin Fei has come to answer the above questions. The reasons why computers often crash and how to solve them. Many people do not know why computers often crash. Now let's take a look!

Now, computers are close to popularity, which provides great convenience for people to work and study. However, "computer crash" has become a problem for ordinary computer users. Whenever the computer starts up, or starts the operating system, or uses some applications, or is ready to exit the operating system, the "beast" of "crashing" may come at any time. It can be divided into several points according to the causes and preventive methods of "crash".

First, the reason for the "crash" of the computer:

1. Improperly caused "crash" 1. BIOS settings. Each hardware has its own default or specific work environment, so it cannot exceed the work permission setting, otherwise the hardware will crash because the hardware does not meet this requirement. For example, a memory stick can only support DDR 266, but it will crash because the hardware does not meet the requirements because it is set to the specification of DDR 333 in the BIOS setting. If it can work normally in a short period of time, with the increase of use time, electronic components will gradually age, and quality problems will also lead to frequent "crashes" of computers.

two。 "crash" caused by hardware or software conflicts. The "crash" of computer hardware conflicts is mainly caused by the conflict of interrupt settings. When there is a hardware conflict, although each hardware can be barely stored in the system {xx}, it cannot work at the same time. For example, if you can access the Internet, you can't listen to music, and so on. Over time, interrupted conflicts will occur frequently, and finally the system will be overwhelmed, leading to "collapse".

Similarly, this situation also exists in software. As more and more software is developed by different software companies, and it is impossible for these software to be fully familiar with and cooperate with each other in the development process, it is easy for people to call the same DLL or the same physical address at the same time when running these software together, resulting in conflicts. At this point, our computer system does not know which request to process first, which leads to system disorder and computer "crash".

3. The "crash" caused by hardware quality and failure, because at present, some small brands of computer hardware products are often put on the market without going through qualified inspection procedures, and many of the poor quality hardware products are very hidden under the cover of good quality computer hardware, and it is not easy for ordinary people to see. As far as these hardware products are concerned, the cause of the computer crash is directly related to itself. In addition, some hardware failures are caused by long service life. Generally speaking, it is difficult to guarantee the life of memory strips, CPU, hard drives and other components more than three years, which will lead to many hidden "crashes".

4. The "crash" caused by the exhaustion of computer system resources will cause a "dead" cycle inside the system when the computer system executes the wrong program or code, and the already very limited system resources will be put into endless repeated operations. at the end of the operation, it will lead to a "crash" due to the excessive depletion of computer resources. Another point is that a large number of programs run in the computer operating system, resulting in a lack of memory resources in the system, resulting in a "crash".

5. A "crash" caused by the destruction of system files. System files mainly refer to the files that play a key role in the startup or operation of the computer system. Without them, the whole computer system will not work properly, and of course, "crash" is inevitable. There are many reasons for the destruction of system files, and the invasion of viruses and hacker programs is the main reason. In addition, the primary user deletes system files due to misoperation, which will also lead to this consequence.

6. The reason for the "crash" caused by poor heat dissipation in the computer is that the main component of the electronic components in the computer is silicon (this is an element in which the working state is greatly affected by temperature). When the computer is working, the temperature of the electronic components will rise, and the phenomenon of electron transfer will occur on its surface, thus changing the current working state, resulting in a sudden "crash" of the computer at work.

7. The "crash" caused by the misoperation of the junior user. For beginner users, some misoperations in the process of using the computer will also cause the system to "crash". For example, hot-swappable hardware, shaking the computer during operation, deleting files at will, or installing software that exceeds the basic hardware setting standards may lead to a "crash".

8. The "collapse" caused by other aspects. In addition to the above reasons, there are many strange reasons that may cause the system to "crash". For example, the voltage fluctuation is too large, the reading ability of the optical drive is reduced, the quality of the floppy disk is not good, the virus or hacker program is damaged, and so on. In short, there are many reasons for computer crashes.

From the above points, it can be seen that the computer "crash" for ordinary users is not a good thing, but it is not inevitable. As long as users follow the normal computer operation, it is believed that the probability of "crash" will be reduced to a minimum.

II. Prevention of computer "crash"

1. Make sure the correct Bios settings are set. The settings in Bios must be appropriate. Incorrect Bios settings can cause you to crash when you run Windows.

3. Clean the chassis regularly. Too much dust will cause poor contact between boards and cards, causing the system to crash in operation, so the chassis should be cleaned at any time and do not let too much dust accumulate in the chassis.

4. Persist in conscientiously investigating and killing the virus. Do not easily use CDs or floppy disks of unknown origin. For attachments in the mail, check them with antivirus software before opening them.

5. Shut down the computer in the correct order of operation. Do not turn off the power before the application software is running normally, otherwise it will cause damage or loss of system files and cause a crash during startup or operation.

6. Avoid multitasking. Do not run other software while performing disk consolidation or checking the hard disk with antivirus software, otherwise it will cause a panic.

7. Don't be too innovative. The drivers of all kinds of hardware do not have to be updated at any time, because the newly developed drivers often have bug in them, which will cause damage to the system and cause the system to crash. The latest one is not necessarily the best.

8. When uninstalling the software, use your own anti-installation program or the installation / uninstall method in Windows, do not delete the program folder directly, because some files may be shared by other programs, once you delete these shared files, it will cause the application software to crash.

9. When setting up hardware devices, it is best to check whether there is a reserved interrupt (IRQ), and do not let other devices use the interrupt number, so as not to cause interrupt conflicts and cause system crashes.

10. When surfing the Internet, do not open too many browser windows, otherwise it will lead to a shortage of system resources and cause the system to crash.

11. If your machine doesn't have a lot of memory, never run a memory-intensive program, such as Photoshop, or it's easy to crash at runtime.

twelve。 For system files or important files, it is best to use implicit attributes, so that these files will not be deleted due to incorrect operations, causing the system to panic.

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 modification failure.

14.CPU, graphics cards and other accessories generally do not overclock, if you do need to overclock, you should pay attention to the temperature of the card after overclocking, CPU, graphics cards, such as long-term abnormal frequency and temperature, light work automatically restart or crash, heavy cases burn CPU, graphics card, motherboard.

At the end of this article, I hope it will be helpful to you.
