What's wrong with the computer screen flashing like this all the time?

First, the driver problem, which is also an important reason for the screen display, mostly appears after changing the driver version of the graphics card, or it may be caused by the damage of the driver file. The solution is simple, reinstall the official graphics card driver.

Second, the temperature problem, this problem is not only because the motherboard's graphics card, processor, memory and even chipset are overheated, which often happens in summer, but in winter, if the radiator falls off and the fan stops running, it is likely that the indoor hard disk temperature is too high, which cannot be ignored. It is also recommended to open the chassis to check the installation of each radiator, try to open the chassis to run the game, and see if the screen will be drawn again, and the fault will disappear after a period of time.

Third, power supply, including power supply and AGP/PCI-E 16X power supply for the motherboard. If the graphics card does not get enough pure current, the screen may also appear. The solution is to disconnect the CD-ROM drive, independent sound card and other unnecessary hardware to reduce the load of the whole machine and try again.

Fourth, there are many reasons for graphics card problems.

It is possible that the golden finger is oxidized or there is too much dust. Try cleaning it up. The oxidized part can be wiped with rubber.

If it is ineffective, it is recommended to contact the dealer for replacement or return to the factory for maintenance.
