Problem:Freezing for about 15-30 secs while playing a game, but has also happened while just watching videos, then flashing to the desktop greeted by this error message, AMD Display drivers have crashed and recovered successfully.
The problem started randomly while playing apb reloaded, even on the lowest settings in all areas, Also when playing Fallout 3. The same problem also occurred while i had a GeForce GTS 250 graphics card in. Even after updating all of my drivers, most of them were already up to date, it still happened. I just did a clean install of windows 7, first game i tried to play was Dead Frontier, a browser shooter. 30 secs into the game my computer freezes and the display drivers crash
If happened with two diff cards then you should check your RAM with memtest. It could be faulty board also. Altough you have 850W (don't know which and how old) it may be faulty also and not providing stable current and voltage to PCI-E slot.
Run furmark to stress your GPU and to see will happen in there.
Also you may try to roll back drivers by couple versions.
