Does it run the POST tests? You should see it flash the lights on the keyboard, and access each drive in turn as it tests them. From your description, I'd suspect the video card first, although it could be any of the other cards or drives. Since everything spins up, it sounds like the 12v side is OK, but if you've go something shorted out in the 5v side the power supply would detect that and refuse to power the logic circuits.

No flashing lights and the drives are not connected.
