power supply problem? - weird

[szman86]

I usually leave me computer on most of the time, but the other day I shut it down for a few hours, when I went to turn it on it didnt completely turn on, but started to pulse. I knew it was pulsing because my Epox mb with the digit code leds at the bottom was pulsating on and off, and all my fans were as well. I tried unplugging everything but the gc and nothing changed. I'm completely lost as to what the problem is. Please help.

antec true 380w ps
geforce 6800 gt
anything else that would be helpful?

I have an antec truepower 2.0 550W that is doing the exact same thing- only it never worked.
Anyone have any wise words?
