I upgraded from XP to 7 last friday. Since then, I've had problems running games, but only today I've realised it only happens using DX10.
What happens is within a minute of a game starting (not in menus) my 4870 will lock up and the screen will go black and lose signal. Windows manages to recover the driver giving me time to end the game or try and carry on which then results in the same, eventually requiring a hard reset.
This happens in company of heroes, but not in L4D so I thought it might be related to directx since both games were ok in XP. Now I've just tested Resident Evil 5. In DX9 mode I can play fine but in DX10 mode it crashes instantly.
I've tried catalysts from 9.7 to 9.11 beta and its still the same. The card is definitely not overheating, as gpuz shows normal temps and l4d and res5 dx9 can be played for ages without any crashing.
Any ideas people?
