Sempro slogan

Not a virus! It's not a hardware problem! It's just that the installation sequence is seriously wrong! ! Driver installation should follow the principle of main display first, then other hardware! Even if your sound card and network card are integrated, you can't install the network driver of the sound card before installing the video card! The only solution is to try to get rid of other drivers besides the motherboard chip, including sound cards and network cards! Reinstall the graphics card driver and the problem will be solved!
