I just finished hooking up the last IDE cables and power cords, and all i get is the a quick spin from the fans and then nothing. If I push the power button again, the fans will not even spin again. The only way they will spin is if I unplug the power cord form the back of the machine and then hit the power button. Then again, the fans only spin for a split second and then NOTHING! Is this a problem with the CPU?
