I have a very irritating problem when using the Aero environment on Windows 7 x32 system leads to random occurrences of errors with atikmdag driver, when you turn off Aero error disappears. I use the latest Catalyst 10.7 drivers and I do not know what to do. I sent a request for assistance in ATI but no response. What would solve my problem? To mention the card is not overheating (40 C) and power is good only as old nForce2 A7N8X boards, help!
