Moved parts to new case, now PSU not turning on

Not entirely sure that the PSU is my problem, so this might not be the correct place for it, but let's try.

I got a new graphics card (a GTX 570) and a new case yesterday.

I swapped everything to the new case, hooked everything up, and now the PC won't turn on. When I press the power button, the PSU fan spins for about half a second (not even making a 1/4 of a rotation, I would say) then stops, and nothing else happens at all.

I've double-checked to make sure I have everything plugged in properly. I checked to make sure the PSU could support the new graphics card (specs below), and swapped it out for my old graphics card anyway just in case (with the same results).
I saw the sticky about testing with a multimeter. I don't have one handy, but I should later today. In the meantime, I'd appreciate any input on what might be the cause.

My main concern is just that all I did was swap the parts over to a new case. Other than static electricity damage, I don't see what could have caused this, but then again I'm not very knowledgable about tech stuff anyway.

Thanks.

Specs:
Graphics card: Geforce GTX 570
Old graphics card: ATI Radeon HD 5770
PSU: OCZGXS700
Mobo: Gigabyte GA-P35C-DS3R
RAM: 2x 1GB Corsair DDR2, 2x 1GB Ballistix DDR2

My first concern would be the motherboard mounting. Confirm you have one standoff and one screw for each mounting hole (usually 9); no more and no less.

It may be a good idea to take a short step back and benchtest your sys.

PS: Confirm you have two aux PCI-e power cables connected to the new card. Your HD 5770 used only one 6-pin.

I do have two vacant areas for screws. I didn't think it mattered. I will fix that asap.

Will bench test now.

Yeah, I had two PCI-e power cables in my card.

A missing screw is not that much of a problem. But it is critical that there are no mis-positioned standoffs.

You need to have one standoff (no more-no less) for each mounting hole in the Mobo.
Personally, I would want a 750W minimum better quality PSU for the GTX 570.
OCZ are OK but not top quality.

I set up everything basically outside of the case, and it's working fine now. Just the case fans and my dvd drive aren't hooked in. I guess it was something to do with the vacant standoff places. I'm going to get everything back into the case, more properly this time, and see what happens.

Also, I should have mentioned, all my parts were super dusty. I got it cleared out a lot yesterday, so I don't think that was the cause, but it could be possible.

Thanks for the help so far pals.

I came across this issue after taking the best of two PC's and putting it all into one case. Both computers worked prior but no need for two so i made one. Anyway my point is to check the little battery on the motherboard. I did with a meter and it was dead. Changed it and I have one new PC . I don't know if this is common knowledge but it helped me. As this site has helped me in the past I can finally contribute ha.
