Just started today. Server shuts down and when it attempts to start up, it shuts back down after 1 second. I can hear fans start and then stop. They start and then stop. Over and over again, until after a few moments, it just stops. Lights on Power Supply and motherboard are on by the system is not on. If I pull the Powersupply out and then put it back in it will start up but only last for a few moments.
