I installed a new motherboard the other day. I made sure it was compatable with all my hardware, and installed all the hardware and connector pins according to the motherboard diagram.

Some basic information, I'll add more later.

AMD Athlon 64X2 2.2Gig X2
Biostar Motherboard T-Series
4-1 gig DDR 333Mhz (has jumper set to DDR)
Geforce 7950 512MB GPU X2 (1Gig) (chip set to Normal)
Killernic Network Card
Seagate 120Gig Harddrive (primary), Seagate 400Gig Harddrive (secondary)
Phantom 500Watt PSU

At first it would flash the blue screen at me when I tried to install fresh copy of windows (saying somthing to the effect that it tried to access a thread it did not own). I took everything apart and put it back together and the installation went through. Then another problem occured:

If I turn it off and try to start it back up again the fans and lights will turn on but not the cpu/harddrives. When I turn off the PSU and try turning on the front power button again it will momentarly flash on again but turn off (showing residual power). When I turn on the PSU it will turn the computer back on without me ever touching the power button again. Not all the time, but most of the time. Basically, I have to toggle between the PSU switch and front power switch until the POST is able to start and then windows will run normally (until I turn it off or restart, in which I have to start over).

Has anyone seen this before? I think the PSU has gone bad but when the POST starts it shows all voltage normal (when its able to come up). It could be the system trying to draw too much power but my PSU is a phantom 500 (should be enough right?).

Anyway, any help is much appriciated!
