nvidia 7600 gs problems

[mech_911]

I have tried everything I can think of from flashing the bios to reinstalling my OS and updating all the drivers. Here is the problem I have an ASUS P5S800-VM mobo socket 775 running a 3.2Ghz dual core processor. 1 Processor hyper threading. I bought a 7600 gs video card to replace my old 6200gt. When I play any games now I get lines and screwed up grophics all through the game. I have a 450W PSU and 2 gigs of ram in it. Everything looks good but still the same thing. Thought it was a bad GPU so exchanged the card no help. Any suggestions?

Hi

I can only think of updating the graphics driver.

I have tried graphics drivers from nvidia, bfg, asus, and omega. I am running vista ultimate now, My bios is updated to 1023 beta version 3. I even tried removing the hyper threading on my cpu. Over clocked the cpu and gpu, ready to trash nvidia and go with ati but was told ati and sis chipsets don't play nice together.
