Causes of computer system crashes and prevention methods

Today's computers are almost universal, providing great convenience for people to work and study. However, the computer's "crash" is for common computer users, but it becomes an annoyance to get rid of it. Whenever the computer is started, or the operating system is started, or some applications are used, or are preparing to exit the operating system, the "zombie" and the "fierce beast" may be at any time. So how can we avoid computer crashes? Next, I will introduce the cause of the "crash" and the prevention methods in several ways. I hope the following article can help my friends who encounter such problems.
I. Causes of computer crashes:

1. "crash" caused by improper BIOS settings"

Each type of hardware has its own default or specific working environment, and cannot be set without any permission. Otherwise, the hardware will crash because it does not meet this requirement. For example, a memory stick can only support DDR 266, but it is set to the DDR 333 specification in BIOS settings. In this way, the hardware fails to meet the requirements, even if it can work normally in a short period of time, electronic components will gradually become aging with the increase in use time, resulting in quality problems will also lead to frequent computer crashes ".

2. "crash" caused by conflicts between hardware and software"

Computer hardware conflicts mainly result from the conflict of Interrupt settings. When a hardware conflict occurs, each hardware can barely coexist in the system, however, you cannot work at the same time, for example, you cannot listen to music when you can access the Internet. After a long period of time, the conflict of interruptions will occur frequently, and the system will be overwhelmed, resulting in a "crash ".

This also exists in the software. As different software companies develop more and more software, and these software cannot fully familiarize themselves with and cooperate with each other in the process of development, when these software runs together, it is easy for everyone to call the same DLL or the same physical address at the same time, resulting in a conflict. At this time, the computer system does not know which request should be processed first, causing system disorder and causing the computer to "crash ".

3. Hardware Quality and failure caused by "crashes"

At present, some small brands of computer hardware products are often put on the market without passing the qualified inspection procedures. Among them, there are a lot of poor-quality hardware products that are invisible under the hood of good-quality computer hardware, which is not easy to see by ordinary people. For these hardware products, there is a very direct relationship between the causes of frequent computer crashes. In addition, some hardware faults occur due to the long service life. Generally, the lifetime of memory, CPU, hard disk, and other components is hard to be guaranteed after more than three years, which also produces many hidden "dead-end" problems.

4. "crash" caused by depletion of computer system source"

When a computer system executes an incorrect program or code, it will lead to an "dead" loop inside the system, originally, very limited system resources will be invested in endless repetitive operations. When the calculation ends, the computer will exhaust the resources and cause a "crash ". Another point is that a large number of programs are run in the computer operating system, resulting in a "crash" due to insufficient system memory resources ".

5. "crash" caused by damage to system files"

System files mainly refer to files that play a critical role in supporting the startup or running of computer systems. If they are missing, the entire computer system will not be able to run normally. Of course, "dead" will be inevitable. There are many causes of damage to system files. Viruses and hacker programs are the primary causes. In addition, deletion of system files may also result in incorrect operations.

6. "crash" caused by poor computer internal heat dissipation"

Because the main component of electronic components inside the computer is silicon (this is an element that is greatly affected by temperature ). When the computer is working, the temperature of the electronic components increases accordingly, and the surface of the computer will be subject to electronic migration, thus changing the current working state, resulting in the computer suddenly "crashed" during work ".

7. "dead" caused by incorrect operations by novice users"

For novice users, some incorrect operations during computer use may also cause system crashes ". For example, hot swapping of hardware, shaking the computer during operation, deleting files at will, or installing software that exceeds the standard set of basic hardware can cause a "crash ".

8. Other causes of "crash"

In addition to the reasons described above, there are many strange reasons that may lead to system crashes ". For example, high voltage fluctuations, decreased drive reading capacity, poor disk quality, damage to viruses or hacker programs, and so on. In short, there are many causes of computer crashes.

As can be seen from the above, the computer "crash" is not a good thing for general users, but it is not inevitable, as long as the user operates according to the normal computer, I believe that the chance of "crash" will be minimized. Next, I will introduce some of my experiences on computer crashes.

2. Prevention of computer crashes

1. Ensure correct Bios settings. The settings in the Bios must be appropriate. Incorrect Bios settings will cause you to crash when running Windows.

2. Check the contact information of Computer Accessories frequently. If the Board has poor contact, the system will crash. Therefore, when replacing computer accessories, make sure that the Board has full contact with the motherboard.

3. Regularly clean the chassis. Too much dust will cause poor contact between boards and cause the system to crash during operation. Therefore, the chassis should be cleaned at any time and do not let too much dust accumulate in the chassis.

4. Insist on virus detection and removal. Do not use an unknown CD or floppy disk easily. For attachments in the email, check the attachment with anti-virus software before enabling it.

5. Shut down in the correct operation order. Do not turn off the power before the application stops running properly. Otherwise, system files may be damaged or lost, causing a crash during startup or operation.

6. Avoid multiple tasks at the same time. Do not run other software during disk sorting or checking the hard disk with anti-virus software. Otherwise, the system will crash.

7. Do not seek too much new information. Drivers of various hardware do not have to be updated at any time, because only developed drivers often contain bugs, which may cause damage to the system and cause system crashes. The latest drivers are not necessarily the best.

8. when you uninstall the software, do not directly Delete the program folder by using the built-in uninstaller or the installation/uninstallation method in Windows, because some files may be shared by other programs, once these shared files are deleted, the application cannot be used and the system crashes.

9. When setting a hardware device, it is best to check whether there is a retained interrupt (IRQ). Do not allow other devices to use this interrupt number to avoid interruption conflicts and system crashes.

10. Do not open too many browser windows when surfing the Internet. Otherwise, system resources may be insufficient and the system will crash.

11. If your machine's memory is not very large, do not run programs that occupy a large amount of memory, such as Photoshop. Otherwise, it will easily crash.

12. For system files or important files, it is best to use implicit properties so that these files will not be deleted due to incorrect operations and the system will crash.

13. When modifying the Master Boot Record of the hard disk, 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 card and other accessories are generally not overclock, if you do need to overclock, pay attention to the temperature of the Board after overclock, CPU, graphics card, and other long-term work in abnormal frequency and temperature light, then automatically restart or crash, severe CPU, graphics card, motherboard burned.
