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.

This may seem like a silly question! But do you have a heatsink and fan on the CPU and is it connected to the proper header on the motherboard?

Yes and yes

same problem w/ asus board!

i sent you a PM, but the executive summary is that I have the EXACT same problem with nearly identical hardware, and I am also unable to fix it.
