Have you plugged the PCIe power connector cable into the card?

Well I just triple checked to see if I had power to the card..and it was plugged in correctly...I dont know what the deal it..I tried taking it out and re-seating it ..... I flashed the card with the current firmware thats avaiable for it according to BFG....I was actually getting better preformance from my X1150 that this is replacing...which is actually sad....

Try a different PCI-E power cable... your PSU should have more than one I hope.

There is a fix out for some 8800gt cards that have trouble booting properly with some makes of PS. It is a timing problem. Go to Evga's website and read about it. They have a fix for their cards, don't know if BFG has or not. The Antec is one of the PS that has a boot problem with some cards.

You should contact Antec or vid card manufacturer. I know I've heard this problem before but I can't remember to give you a definitive answer.

Well, since it's pretty new, I'd say start around $220.

I use to have this problem when my pc goes back from sleep mode. Its gone now...

1) i updated my bios
2) downloaded the latest driver
3) run ntune on my pc

here my setup:
1) CPU: q6600
2) MD: Asus Maximus Formula
3) Mem: 4 Gbyte
4) PS: Antec Quatro 850W
5) GPU: BFG 8800GT OC 512

This is not a PS problem, at least in my case. There is nothing wrong with PS and it had more than enough capacity for my load.
