okay, first, i want to make it clear that i mean powering on and not post or boot. do not say a dead cpu will keep a pc from posting or booting sherlock. okay, here is my issue. i have bought now 3 boards. 2 i thought was dead on arrivial (one is for a fact) and i bought a used one because i knew that meant it was tested. it came in today, plugged everything in correctly and no power at all. the power supply is tested. this is the same thing as i was experienceing with the other boards. a couple years ago i had an old AM3+ board and processor. processor was dead but the board still powered on. can it still happen that a dead cpu will stop a board from powering on?
