So I have been having a lot of problems recently with my graphics on my computer in general. The problem happens only after I have installed the latest version of the nVidia graphics drivers. I have a GeForce GT 220 driver version 285.62, Windows 7 Pro, and it should not be having these problems. What happens is best described as random pixelation. The screen randomly has pixels missing and sometimes it distorts images beyond recognition. It almost looks like someone damaged the screen but I know for a fact that that isn't what happened because it only occurs on high graphics usage, like max detail rs or 720p youtube videos. Any ideas for help? My computer is spotless on the inside I clean in constantly.
