Hi, My PC has just started to play up. I go to hit the power button, PC power LED lights up, I hear a 'click', then it powers down. If I hit the power button repeatedly like 3 or 4 times, PC will fire up and boot. Is my PSU about to go? It's not a cheapie - Seasonic Focus 650W. I have other supplies, so may need to test them out. Thanks. Weiterlesen...
