GA-H61MA-D3V (rev. 2.0) Motherboard won't recognise Graphics cards

[Zinbo]

Hello,
I recently got a GA-H61MA-D3V (rev. 2.0) motherboard which seems to work fine apart from that it doesn't seem to recognise any graphics card in the PCI-E slot. I initially installed the GV-N460SO-1GI Windforce GTX 460, the lights come on the graphics card and the fans spin, but it produces no output. The device manager in Windows 7 doesn't seem to recognise that there is any other display adapter other than the internal intel HD Graphics. I've tried updating my bios to f5, I've cleared the CMOS, I've tried disabling internal graphics, and tried changing the inital display to PEG rather than internal to no avail. I've tried using a different graphics card but I have the same result.

If more details are needed on the machine, let me know

Cheers!

I'm not sure if i made it clear, but I'm looking for any suggestions people might have with solving this problem. Otherwise can anyone recommend a motherboard which will support this graphics card?

Cheers again
