I have tried all the connections without success. I vaccumed out some dust (carefully) thinking that that might have caused the problem, but still no success. Obviously some power is getting to the system, because when I plug the cord in the back green light and the amber motherboard light come on. When I unplug it they go off after a few minutes. There are a number of cables and cords not attached inside, but I think that they are for bays that I do not use. I have 2 hard drives and 2 CD/DVD players.
Is there a diagram of what should be plugged into the output wires from the power source. I also checked the wires that go toward the on-off button in the front.
What next?
