My computer often freezes when I'm using it, but the mouse and keyboard still work. The screen doesn't move, and I can't access the task manager. What's going on?

Win78 can basically run with 4G of memory, and XP with 2G of memory. It is easier to use double the memory. If you are not using this number, it is recommended to add more memory (this is a number obtained from practice, not a theoretical number) ).

1) When your computer freezes or freezes, what are you doing on the computer? Can you tell me? I will answer you more accurately based on what you said.

Please describe in detail the performance of your computer before the screen freezes or crashes, and your operations. It may be these operations that caused the screen freezes or crashes. If you have any questions, please ask me (I will follow your instructions) The information provided will answer you again).

Generally, screen freezes or crashes are caused by incorrect operations. Remember not to perform operations that are likely to cause screen freezes or crashes. Do not operate the computer at full load. That is, when you are playing games, watching videos, downloading, or browsing web pages, it is most likely to restart, crash, or blue screen when doing other operations. Therefore, do not operate the computer while playing games, watching videos, downloading, or browsing web pages. Working on something else.

In terms of hardware, if the memory module is small, add a memory module. If the temperature of the CPU and other hardware is too high or the hard disk has bad sectors, it may be caused by inappropriate hardware.

2) If it is related to the hardware, one is that your memory is too low, the temperature of the CPU and other hardware is gray, and there is a problem with the hard disk, use software to repair it. For soft aspects, uninstall the things you downloaded before the accident, and download Win Use the cleaning assistant to detect and kill Trojans, restore the system or reinstall it, but do not operate it at full capacity.
