I am trying to fix an emachine T2862 that would not start. I replaced the power supply first since the old one tested bad and the fans and lights on the motherboard came on. but the hard drive would not spin. I swapped the ram with known good ram and still nothing. I checked the processor in another system and it works fine. I replaced the motherboard and it still does not work. I tried a different hard drive also and nothing. It will not even go to the POST any ideas???
