Inspect the PSU for bulging and or leaking caps.
If it looks good, check the mobo for fets and caps that look off.

All good, try the cmos jumper.

Also, you could be a victim of dead-2ndPCI-e-slot, just like me. My lower (2nd pci-e slot) up and gave out for no apparent reason. Guatam has also experienced this problem. Both of our mobos were Asus boards.

Mine is - Asus M2N32-SLI AMD
Guat's - Asus P5W-DH Intel

Try to boot your top card in the lower slot. if you get a black screen, then your slot is borked.

yea like krag said it sounds like a bad pci-e slot.
