No video signal coming from 4850 X2.

Hey all. I just finished building my new system, but I am not getting a video signal from my card. The fans never turn on either. However, the light on the card does turn on as green, showing that it should be good to go.

I haven't yet tried the other PCIe slot as that means removing the whole motherboard, but I'll guess I'll have to get to that. Anyways, here is the build, and all help is greatly appreciated. I would love to get this up and running tonight if that is possible.

ASRock 870 Extreme3
XFX 750W black edition
x3 445
HD 4850 X2 2gb

I think that's probly all you need to know, plus some. Anyways, thanks for all the help!

    Protip for your next built, start the computer outside of the case before you put together to make sure nothing is DoA and needs RMA. :P I did the same thing quite a few times before I finally learned.

    Anyway, did you try reseating the GPU? And I'm sure you did this but did you plug in ALL of the power cables to the GPU?
  2. Actually, the issue was I missed the 8-pin connector on the Motherboard. Thanks though.
