My computer does not know why the mouse can only be used on the desktop. When I opened the browser, the left and right buttons of the game failed.

This is what happens when the computer is turned on too much. As long as your computer doesn't get stuck, or your computer doesn't open anything, is that ok?

The current system is not the XP era. 4G memory is not big memory, 8G memory is standard. If you play with big things frequently, the total memory is 12- 16. If you use 4G memory, it is recommended to add 4G- 12G memory, which will be much faster.

1) What do you do on your computer when your computer screen gets stuck or crashes? Can you tell me something? I will give you a more accurate answer according to what you said.

Please elaborate on your computer performance before the screen stuck or crashed, and your operation, which may be the cause of the screen stuck or crashed. Ask me if you have any questions (I will answer you again according to the information you provided).

Generally, the screen jam or crash is caused by your incorrect operation. Remember not to do anything that may cause a screen jam or crash. Don't operate the computer at full load, that is, when playing games, watching videos, downloading and watching web pages, it is most likely to restart, crash and blue screen when doing other operations, so don't operate other things when playing games, watching videos, downloading and watching web pages.

In terms of hardware, if the memory stick is small, add the memory stick. The temperature of CPU and other hardware is too high, and the hard disk is broken, all of which are caused by improper hardware.

2) If it is related to hardware, one is that your memory is low, the temperature of hardware such as CPU is high-definition, and there is something wrong with the hard disk. On the soft side, uninstall what was downloaded before the accident, download Win cleaning assistant to kill Trojans, restore the system or reinstall it, and don't run at full capacity if there is one.
