Ok I'm getting to the point fast... I was playing a video game when my PC crashed, i restarted the PC and when the desktop opened everything looked so bad. I cant open games, everything looks like its running on 20 fps even the desktop. I tried reinstalling the video drivers but it didn't work. I opened GPU-Z and noticed that Pixel Fillrate, Texture Fillrate, Bandwidth, Physx and some other things were unknown or missing at all. Also GPU clock, Memory and Shader are at 0. Oh and btw its running hotter than usual. The Graphic Card is a Nvidia 9800GT 1GB. Any ideas what might be the problem?
