long time lurker first post lol please tell me this is a driver thing... glitches in video playback on my gaming desktop, starting right after teh Studio Driver update:

the card isnt new but its never shown anything like this before. temperatures look normal. ive tried a different cable and the artifacts are teh same. id like to know what to test before i convince myself its dead. i also do some photo work on the gaming desktop, so i really need to know whether i can trust what i see on screen right now.
