I recently bought an MSI r7970 lightning graphics card (used)and I tried installing it into my custom built pc and it won't post. When I turn it on all the fans spin for a few seconds and then it shuts off. I know the card is working because it was installed into a test bench at a computer store near me. I then tried trouble shooting I tried running with one ram stick, I installed my old graphics card (thx 560 ti) and the pic booted perfectly, my psu should be more then capable of supplying power to the card (650 Watts). My pic specs:
Core 2 quad q9650
Asus p5nt deluxe mobo
Evga 650 watt psu
8 gb ddrs g skill ram
1 TB western digital hdd
MSI r7970 lightning/ 560 ti

It might not be negotiating the PCIe speeds correctly. You may need a bios upgrade first. From what I looked up on the motherboard specs, make sure it is plugged into one of the blue slots, not the black slot. The black slot is PCIe 1.1 while the blue slots are PCIe 2.0.
