A8N-SLI Deluxe won't power up, fans just jiggle

[Hamlin]

A8N-SLI Deluxe
Antec TPII-550W PSU
AMD X2 4400+
4x512mb ddr400 pc3200
7800gtx
2xWD raptors in RAID 0

Built this system, everything worked, I installed windows, was playing
games, all was happy.

Then I installed a sound card (SB Audigy 2zs) and the USB/Game card
that came with the motherboard.

Booted up, everything normal, detected new hardware...then a few
seconds later everything shut off. Now when I push the power button,
the fans jiggle and then stop. Pushing the power button again does
nothing until I reset the PSU.

I've taken out the new cards, but no luck. Anything else I can do or
did I somehow manage to hose my motherboard?

Could be the power supply.

It has been reported that rarely the use of USB connectors other than
those built into the back panel can fry the nForce chipset. What did
you connect to the "USB/Game card?"

I had almost the exact same thing happen to me a few weeks back with this
board. After elimination of everything else, I returned the board and got a
replacement.
