All right - as I said in my earlier topic, my computer remains on for no more than three seconds and shuts off. I have already determined that it's not the motherboard (RMAd it), not the CPU (tried two separate CPUs), not the video card (took it out), and I just spent fifty dollars to confirm that it's not the power supply. There is NO possible explanation here, except that somebody at Asus hates me. And I'm extremely frustrated.
