Need Help!?

[Notquiteanewbie]

Well I was all set to build my dream machine so to speak
some specs:
Asus p4p800
pentium 4 2.4c
2x256 mushkin 3200
antec 400watt
chieftec matrix case
radeon 9600

anyway i was weaing my wrist strap and took every precaution, however tragedy strikes. I went to put power to awaken the beast, it got power for literally 1 second and shut back down, i looked over everything and made three hypotheses.

1. radeon 9600 is a 3.3v agp card, mobo only accepts 1.5v

2. Bad power supply, never did the paper clip test but power died however when i attempted to remedy things, the mobo led still went on when flipping the switch but absolutely nothing when pushing the button, never heard my fans turn on either, but then again not much can happen in 1 second.

3. bad motherboard

since this was my first new system in a while i couldnt test parts in another machine so that kinda sucked, so just rma'd everything.

can anyone tell me the actually effects of installing a 3.3v in a 1.5 only agp slot, even though they still fit physically, what effects does it have electrically?

anyone think its a power supply problem?

comments are welcome

I have had that exact same problem with that motherboard. Worked fine for a few, then did what you said, then worked fine again. Not buying another Asus motherboard.

I've heard of others having the same issue. IF possible, get a refund on the board and get an Abit IS7-E.

Ditto, mine worked for maybe four days then started behaving exactly like yours. Traded up for an abit, 6 months later and no problems.
