I asked this before but it seems to have been deleted. I have a GeForce GTX 560 Ti that works as I have tried it in other motherboards. I upgraded to a ASUS FM5A99FX Pro R2.0 with a Corsair AX750 PSU. When I tried using the GTX the motherboard does not detect it, nor any other known good GeForce cards. But it does work with a Radeon 6670 HD. The motherboard has a AMD FX 8320 8 core cpu with 16 gigs of memory in 4 sticks and no other cards (either PCIe or PCI). The power supply is 750 watts with the +12 volt rail supplying 62 amps. Both PCIe plugs are plug into GTX. The motherboard uses an AMI Bios revision 1302. There is a more current version on ASUS web page but it appears to deal with an issue with the F8 key on a fast boot so I am very reluctant to upgrade if it will not do anything useful. The mobo runs just fine on the Radeon but obviously I would rather use the GTX.

Does anyone have any suggestions?
