SLI boot issue on Alienware PC

Hi all, first time poster, long time lurker.

Have just bought an Alienware PC... yeah, I know... I deserve whatever problems I get. I bought it from the Dell outlet, and actually got a pretty amazing deal. So good a deal that I couldn't even come close to matching the components with a self-built machine.

Specs are:

Alienware Aurora R4 with Dell OEM motherboard
i7 3970x CPU
Asetek closed loop liquid CPU cooling
32GB DDR3-1600 RAM
SLI GTX 680s
875W PSU
LiteOn 256GB SSD
Sandisk 2TB SATA HDD
Windows 7 Ultimate SP1 x64


The problem seems to arise when I try to boot the machine with both GTX 680s connected. I've removed all but 1 ram stick and 1 GPU and it works fine. I added all the RAM sticks and it boots fine. I swapped both GPUs in and out, and it boots fine, as long as it's only a single GPU in there. I've tried each GPU separately in each of the PCI-E slots and they both work.

When i start the machine up with both GFX cards, I just get a black screen and nothing happens. Doesn't matter whether I have the SLI bridge connected or not. As soon as both cards are plugged in, the PC refuses to post. A couple of times, if I let it sit there for 15 minutes or so, it has eventually popped up with the windows login screen, although it won't display any of the post information beforehand.

For now, I'm just running the machine with a single graphics card, but I've got no idea what might be wrong. First, I thought the SLI bridge might be faulty, but since I get the error even if it's not connected, I think it must be something wrong with the mobo.

Can anyone offer any advice on what might be happening?

Thanks for your time.

Thanks for your sage advice, sir.

Just out of interest, how much would I have to have paid for it to be a "rip off"?

That's what people who can't afford alienware always say.
