There is a blue screen on the computer, both software and hardware are possible, not just the hard disk is broken. In terms of software, you can use the latest antivirus software for virus scanning. If you recently installed a new version of the driver and returned to the original normal version, if the problem is not solved, you can reinstall the system. In terms of hardware, if it is overclocked, first restore the default frequency of hardware; Then check whether there is any problem with heat dissipation, because overheating of hardware will cause data reading and transmission errors; The next step is to use the replacement method to check which part is the problem, of which memory is the most suspected.

Pay attention to the following points to prevent computer blue screen: make manual backup of important registry files on a regular basis; Try to avoid abnormal shutdown and reduce the loss of important files; For ordinary users, as long as they can run normally, the graphics card, BIOS and driver of the motherboard should not be upgraded; Check the optimized system files regularly, run the system file checker to check the file loss and proofread the version.

Insufficient virtual memory leads to system multi-task operation error.

Virtual memory is a unique method to solve the shortage of system resources in WINDOWS system. Generally, the remaining space of hard disk in the main boot area is required to be 2-3 times of its physical memory. In order to make full use of space, some enthusiasts cram their hard disks full and are busy remembering the harsh requirements of WINDOWS. As a result, the virtual memory has an operation error due to insufficient hard disk space, and a blue screen appears. To solve this problem, it is very simple. Try not to fill the hard disk, and often delete some temporary files and swap files generated by the system to free up space. Or you can manually configure the virtual memory, select Advanced, and transfer the default address of the virtual memory to another logical disk. This can avoid the blue screen caused by insufficient virtual memory.

2, CPU overclocking leads to operational errors.

Overclocking is a common occurrence for enthusiasts, so various failures caused by overclocking are inevitable. Overclocking itself is to achieve higher performance on the original basis. However, due to overload operation, too many internal operations and overheating of CPU, the system runs incorrectly. Some CPU overclocking performance is better, such as Intel Celeron processor and AMD-K6-2 processor, but sometimes there are some inexplicable errors. (For example, I tried to read the Intel Celeron 300A when it was overclocked to 450, and the floppy drive didn't accept the command). CPU below Intel 200 and AMD-K5 have poor overclocking ability. It is suggested that when the high-grade CPU is overclocked, it is necessary to do a good job of heat dissipation, and it is best to install a large fan and add some heat dissipation materials such as silicone. As for some low-end CPU, I suggest that you don't overclock it, so as not to overclock it to achieve the expected effect, but often the blue screen will affect the normal speed of the computer.

Second, the incompatibility or damage of the storage tape will lead to operational errors.

This is the most intuitive phenomenon, because this phenomenon can often be seen as soon as it is turned on, and the computer can't start at all. The screen prompts that there is something wrong with the memory, asking whether to continue. This error is caused by physical damage of memory or incompatibility of memory with other hardware. At this time, only another memory was changed.

Third, the phenomenon of being attacked by unknown programs or viruses, as long as it is encountered when we are surfing the Internet at ordinary times, may expose our IP when we are surfing the Internet, especially when we enter some BBS stations, and be attacked by hackers with some software. In this case, it is best to install some defense software on your computer. Then log in to BBS to make security settings and hide your IP.

4. The abnormal startup of the CD-ROM drive when reading the disk is that the CD-ROM drive has a blue screen due to misoperation when reading data. This problem does not affect the normal operation of the system, just eject the CD or press ESC.

The above are several reasons that lead to the blue screen when I repair the computer, and there may be other inexplicable problems that lead to the blue screen of the computer. In any case, after encountering such a problem, we should carefully analyze the causes of the problem and then start to solve it.

Start-Programs-Accessories-System Tools-System Restore. If the problem is still not solved, it is a system problem. Better reinstall the system.

If the problem is solved every time the system is reinstalled, and other problems appear after running for a period of time, then the hardware fault can be eliminated.

Software conflicts can also lead to system crashes or viruses at work.

It is not necessarily that there is something wrong with your machine.

See if you have installed a lot of pirated software. If it is not too necessary, I suggest you uninstall a part. First, improve the stability of the system; Secondly, the system can also be slimmed down.
