fuzzy purple? Well this started to happen after I downloaded a game called Halo 1 for PC. It worked fine for the first day. Then I remember changing some features in the "Video" section, i changed something to high detail and some other things. Then soon after that my cpu started to act wierd it changed into purple fuzzy all on my screen and when i tried to drag anything on desktop it makes it even worse and it leaves duplicates. Now when ever I play any other game it has the same problem, even when I close the game my whole desktop is like that, and anything else that I open up. I uninstalled the game just incase there was a virus which I'm sure wasnt.
