My PC will not power up after being unplugged. The LED light on the motherboard is blinking. I've checked the Power Supply using an Antec Power Supply Tester, that seems to be fine. I replaced the battery on the motherboard.
It's a home built PC, built Jan 2007.

Any assistance/ideas would be greatly appreciated.
