From time to time while playing Skyrim, I will get a freeze (pretty common, no big deal, I know), HOWEVER if I try to restart Skyrim, I will get graphical artifacts like crazy. Black lines shooting everywhere. The problem does not go away until I restart my computer and sometimes I get a c++ runtime error. This isn't my GPU's fault because after Skyrim artifacted, I tried running a Furmark stress test and everything was fine so I know it is only Skyrim that causes this problem. Any ideas?
