If you can not get energy to come on and the hard drive to spin up when bypassing the motherboard and forcing energy on, either the ATX power supply has failed or the difficult drive does not present a adequate electrical load for the switching power supply to operate. Diverse personal computer hardware calls for unique energy provide wattage to operate appropriately and effectively.
