ok weird one i installed the NVIDIA GeForce Quadro Driver 337.12 Beta update last night and this morning my living-room PC looked like this in video playback:

Little colored blocks, flickering lines, sometimes a whole strip of the screen goes green for a moment. It doesnt crash, it just looks horrible. My stomach dropped cuz artifacts usually mean dying hardware, right? But its supsicious that it started exactly after the update. How do I tell which one it is without spenidng money?
reading release notes like its a horror novel
