What happens to the display flower screen due to a video card failure

One is the graphics card heat not hot, after working for some time, will cause the display suddenly black screen or flower screen. If you are in normal use of the computer to appear this problem, it may be important to check the graphics card radiator, look at the cooling fan has not stopped, the heat sink is hot, if there are two situations, you should focus on improving the graphics card cooling system.

Second, video memory is damaged. Video memory is an important part of the graphics card, especially the memory in the computer, which is responsible for the temporary access of the data. When the video memory is damaged, when the system starts will appear the phenomenon of flower screen, the character confusion, can not distinguish. If there is a problem with the video memory, you must replace the video memory, because the replacement of video memory is a very high technical work, so recommend the repair.

The third is the cause of the virus. Some virus occurs when the flower screen, then the flower screen is not the hardware, so if you restart, you can also troubleshoot, but the root of the solution is to use anti-virus software to completely kill the virus.

Four is the video memory speed is too low. When the video memory speed is too low to match the speed of the host, it will also produce a flower screen phenomenon, when only able to replace the graphics card. (But for now, the video card is already very high, and generally does not appear to be this problem)

Five is that the display card conflicts with some applications. This situation is often reflected in the exit of some applications will appear flower screen, random keystrokes are no response, similar to the crash, the general restart the computer, the fault can be ruled out.
