I would guess it is the PSU. at any case, get it returned on warranty and if you still have an issue, then its the video card. We can say for sure that the PSU isnt putting out enough amps.
got some good news, got my desktop back today.. in the description it says the CMOS Jumper was missing.. no idea where that is (but they said it'd been on Mobo), and how it gotten out of there
