Left my Desktop unplugged for the summer since I was out of town. I came back and started it up only to find the GPU is showing artifacting on Windows items such as the task bar and settings app, but other apps like chrome are artifact free. Also when I try to start a game the display driver crashes. I used DDU to uninstall drivers and it stopped the artifacting but it came back when I reinstalled drivers. I've only had the card since November, is it cooked?
