You need a better PSU.

650w reccomended by AMD, though I needed 700 for mine.

Rosewill isnt very good. I wouldnt trust my rig to it.

IDK if power is the issue though. It should boot up at least.

EDIT: is PCI express enabled and set to first init in the BIOS?

The pc does turn on, everything is running. Its just on my monitor it says no signal

How do I set that in the bios? I cant see it

BTW: I think its the psu now. I think im going to buy a corsair 850. I heard Corsair is the best at its price

Corsair, OCZ, cooler master are the ones I trust.

Plug the monitor into the onboard video and it will either run (meaning the video card is doa or not enabled) or it will say no signal which means the video card took, but isnt working for whatever reason.

I managed to get my 4850 x2 to boot on a 580 watt once...

Do you have another video card to try?

or possibly another computer to test the card in?

Man, I don't have another gpu. And my other board is gone. I guess I should buy a psu off newegg and hope for the best?

Have you tried connecting the monitor to both outputs on the video card?
