I have ASRock P55 Extreme LGA 1156 that will not power on. When I first built the computer, it had a minor (5-10 seconds)This delay then went to 30 seconds and now does not powering up at all. The onboard power switch and reboot switch are both lit up but unresponsive. Previously I have unplugged the power supply from the wall outlet and plugged it back in to get it to work.
Do you think this is a power supply gone bad or motherboard?
