Hello, everyone. The meeting will answer your questions. What is the cause of the computer blurred screen, and many people do not know what the reason is. Now let's take a look at it.

Answer:

The display card conflicts with the Chinese system: when you exit the Chinese system, the computer screen will appear, and any key will not respond, similar to a crash. How to deal with it: enter MODEC080 to solve the problem at this time; the display card main control chip has poor heat dissipation effect: this will also cause stripes on the computer screen.

How to deal with it: replace the higher-speed video memory, or slow down the host; memory damage: when the memory is damaged, when the system starts, characters will be confused on the screen.
