I volunteered to help my friend move his old Dell P3-700 into a new aluminum case. (pls don't ask why he would spend money on a fancy case and put a clunker in there, I couldn't even begin to explain)
Anyway... when I try to fire it up, all I get is a small buzzing noise from the power supply (also new), and no indications of power anywhere else. If I disconnect the motherboard and just connect the front bezel controls, (lights, motorized front panel, etc) the front comes to life like it should.
The front panel has a connector that fits in between the p.s. connector and the motherboard (so it's powered even when the pc is off).
Any ideas/insights are appreciated. I hope I didn't fry something. (Then again, if I did, he might have to buy some real hardware)
