i installed the NVIDIA Forceware Drivers (Windows 9X/ME) 56.64 Certified update last night and this morning my gaming desktop looked like this in games:

Little colored blocks, flickering lines, sometimes a whole strip of the screen goes green for a moment. It doesnt crash, it just looks horrible lmao My stomach dropped cuz artifacts usually mean dying harwdare, right? But its suspicious that it started exactly after the update. How do i tell which one it is without spending money?? pls help 馃檹
