Mobo: Asus m4a78t-e (latest bios rev)
Chipset: amd 790gx / sb750
cpu: AMD Phenom II x4 955
ram: OCZ Reaper 2gb x4
Windows 7 Ultimate x64
Video card(s) - BFG Tech nVidia GTX 280 pci-e
--also tried two different 8800s.
This mobo comes with onboard video ati 3300. Current win7 catalyst drivers are installed for that.
Tried many things to get windows to see the 280, but no luck. Won't list in device manager, so can't install drivers. Narrowed down to either: bad pci-e on mobo; problem with win7; conflict with ati drivers; or I'm missing something crucial in bios.
Anyone point me in the right direction?
