Okay, I tried to be extra thorough to get rid of all graphics drivers and then reinstalled my old 5770 with the latest drivers. I am still getting the same freezing problem. In addition, the computer is now no longer detecting one of my hard drives and the side panel case fan is no longer running. Maybe this is all a power issue? I don't have another desktop power supply that I can switch out to test with. Anyone know how I would test/look into this?
