I recently replaced my 7900gs that burnt out with the 7900gtx, and for some reason windows thinks it's a quadro NVS 510M. I had them send me another one and it has the same problem. BIOS reads it properly but windows won't let me manually install drivers. It says the hardware isn't compatible. Note: I flashed my BIOS to the latest version and it didn't help either. Is there some kind of setting I need to adjust to make it work?
