What piss me off is that i don't know what is causing this issue. Everything has been checked by the rules, everything is working as should be, the system runs fast and stable.
I had same prob, but i got lock ups to but this only ever happened on desktop not in games, so discovered it was a vista problem, and believe it to be narrowed down to Aero so i went into safe mode uninstall driver, then restarted and reinstalled driver then made sure to select aero and apply rather than let windows change to it itself and now i dont have anymore problems.
