Ok, so today I got my BFG 9800GX2 and Cooler Master Real Power Pro 750W. now I put the PSU, connectin the 24 pin cable (ATX), the 4 pin cable (ATX 12v), my HD cable, DVD, fans, leds, and the new card. now when pushed power it powered and agter a sec powered down, and then automaticly it did it again for 2 times and powered down. so I pushed power again and it powered like it should, but there's nothing on the screen, it's like it doesn't get a signal or something. what to do???? Thanks!

I had the same problem.

Found out its not the card it was me, reseat the card.. What i noticed was that the backplate was pulling on the card as you tighten it to the chasis, so the front kinda comes out of the slot?

1. Take out Card and Reseat it front in first make sure its seated 110%
2. Dont SCREW the card in and boot it up. Thats how i tested it to make sure video was working before i screwed it in.

I'm almost certain your issue is the same as mine. Cuz It happened twice to me. :) (im 110% sure your having the same issue as I)
 
Nah it's not it, I've reseated it 3 times, and it looks all the way in the slot. thanks anyway mate
 
Take the new card out and put your old one in. Then try. If it does not work switch the older psu with the new one.
 
make sure you connecting your monitor the the bottom dvi slot, the bottom is the bootable top is additional display (non-bootable)
 
i always put my dvi connector from my monitor on the dvi the nearest to the board..try that... also try to clear your cmos if anything .. who knows maybe your board is freaking out at the card??
 
I too have the same problem, and I think I've narrowed it down to a motherboard compatibility issue with SLI single slot cards.

I put my 9800 GX2 in an Asus A8N32-SLI and it worked. For some reason this didn't work with my first 9800 GX2. I RMA'ed that card and it works in the A8N32-SLI.

Of course I want it to work in my sig rig, which is an Intel Q965 board. So knowing that the 9800 GX2 was good, I put a 7950 GX2 in the Q965 system, and guess what, no video!

So am going to update the BIOS to the latest version I can find. Its a Foxconn motherboard.

So my guess is that you are having the same issue. I've not been able to track down any information reguarding motherboard compatibily with the 9800 GX2, but its not 100% with everything it looks.
