Windows 7.64, Areo classic
Mushkin 8GB 1333
OCZ vertex3 240
6950 Drivers 12.1, not over clocked, never been overclocked, huge case, plenty of airflow.
All games, BF3, Wargame EC, SupCom2, dosnt matter, any game worked fine and stable aslong as I loaded the game before it happend.
Artifacts arnt that of typical overheating. Screen would freeze on a blue screen, but not the typical bsod. There no crash dump text etc, just a blank light blue screen.
Like I said, I have moved just the graphics card into a entire new system, and still the 5 min issue. But only in a windows enviroment, eg surfing the web, multimedia etc. If I boot, and dont touch a thing, its stable. As soon as I touch it, if im not already loaded into a game. Its freezes.
You would think if its a graphics card, its working hardest during a game?
Maybe bad driver making the idle fan speed not detect the gpu overheating at minimal load.... ??? Hence games OK, but on windows screen = after a while bad?
Load up your driver thing that shows you the gpu temps and sit for 5 mins sipping a cup of tea in windows while you wait for the artifacting to begin. If it gradually heats up then there's your problem.
Monitoring fan speeds is also advisable.
