im currently using 11.9... Ill try downgrading to a lower version, though i doubt that will help...
Also i ran memtest for about 3 hours/ 3 passes... it found 0 errors D:
its annoying not knowing where the problem is coming from
Edit: some users said turning off Aero on windows 7 fixed the problem.... Can you try this? I cannot I will be away from my computer for a while as we are moving soon
