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?

Will attempt hooking up my desktop's PSU to it when I get the chance, but it won't be tonight. –  Corey D Feb 25 '10 at 3:33
    
Do any of the fans/disk spin? If not then its most probably is a PSU issue. If the fans/disks do spin then try booting with the bare essentials. Like Mobo + CPU + 1 RAM Stick + (GPU if no onboard available) –  IUnknown Jan 24 '12 at 21:56
