i am running a GA78LMT-S2P mobo, with Phenom IIx4 B50, 8GB RAM, and Radeon HD 6450 graphics card, with windows 7 ultimate OS. My screen/system keeps freezing, and will sometimes come right back & display the error message, "your display driver has stopped working",or will cause the system to reboot. I have already tried update the drivers, as well as roll back the drivers, and even uninstall/disable, None of which had any change. The only other settings i can think of that might help, would be the High Performance GPU clock setting & the High Performance memory clock settings, but I am not sure how to even go about setting them properly. can anyone help?
I had gtx 560 once which gave me the "your display driver has stopped working" error message,I tried a lot of things but nothing worked so in the end I got the card exchanged with an amd hd 6870.So may be your card is faulty.
