Power blip on new comp, help...?

Ok, here's the problem... I build a computer and get the thing going. As I'm trying to install windows onto the harddrive the computer will just restart. Nothing is overheating as far as I know and now any time I try to turn on the computer I get a power blip, the fans spin a bit and the lights on the mobo fire then go off. WTF is wrong? I'm guessing power supply, but I'm not sure.

SPECS

Abit IC7-MAX3 mobo
p4 3.0
radeon 9800xt
1gb of ocz pc3500 ram
and the powersupply is stock in a 50 dollar case, 350watt psu
100gb western digital hdd

Any help/suggestions would make me happy. Thanks
 
only 1 person has viewed... kinda important, anyone have an idea of what's wrong?
 
Just a WAG (Wise A$$ Guess) here, but do you have that 9800 plugged into the same power lead as your hard drive?
I had my 9700 plugged into the same lead as my hard drive and it caused mine to lock up (although it never restarted). Mine worked fine with my Epox board while hooked up to the hard drive lead (after I replaced my 300 Antec with a True 430), When I installed my NF7-S with a hard drive on the S-ATA and the 9700 on the same lead I had problems. Those cards are power hogs and can cause problems sometimes.
Another possibility is that the PSU isn't strong enough for that video card.
 
It was a power * blip *you say? :D

PSU is a possibility. As we all know, watts mean little when it comes to a PSU, its how it is built that matters. Still, it should provide enough juice to power it. (Though it might cause it to redline, eventually burning it out)

There are several other possibilities such as a bios failure or a basic failure on the mobo. Since it isn't even POSTing, it probably isn't memory. Hmmm...

Can you give us a little more history on the system? I'm guessing that everything is new on it, but I could be wrong.

Anyway, the best approach to this is probably to strip it down to a minimum number of components (and replace any components that you can with known-good equivalents... aka dust off your old video card and try plugging that in) and then slowly rebuild it until you the problem appears.
 
turns out the psu that came with the case was bad. I popped a different psu in and it ran like a raped date. Thanks for the help though.
