I was just rebuilding an old desktop PC to be used as a HTPC and the LED on the motherboard that indicates when there is power is blinking fairly rapidly. The only way I can get the machine to boot is to press the power button immediately after plugging it in, and even then I cannot make it into the BIOS.

The power supply has more than enough juice to power all of the components, and is from a reputable manufacturer.

The motherboard is an Asus and is about 4.5 years old.

Is my power supply hosed? Or is it my motherboard?
