When I turn it on, the fans and everything turns on except the computer doesn't boot up.

The only difference is that when I press the power button on my computer - the power LED lights for a split second, and the CPU cooler fan spins for a half spin.

The mobo light is lit when the PSU is plugged in and powered on.

Because of this it is difficult to determine whether the problem is with the motherboard or the PSU when a computer shows no signs of starting up.

The purpose of the procedure is to determine if the problem is with the motherboard or the PSU.

I'm out of ideas, and I have no computer other than this work laptop. Asus A8N sli-premium mobo I'm not too hot on the idea of plunking down $600 for new mobo/ram/cpu as recommended in the Hot Rod, though I'm already thinking I might have to do just that. I'm surprised that it was the PSU since, as I said in the OP, I tested it by jumping the pins and read proper voltages at every lead.

It looks like you've tried just about everything I would have suggested. Regardless, here I am, with a working computer and a new PSU.I tried clearing CMOS, taking the surge protector out of the equation, changing RAM, even P/S etc.Finally, I tried removing one case fan from the equation (an Antec, BTW). Eventually, it booted even with the case fan connected. things to get that board to work again, but it did, after more than a week of not working.My PC shut off out of no where so I'm not sure if the old power supply took anything else out with it.EDIT: Seems like everything boots up, all the lights turn on, but nothing on the screen and the CD drive won't respond when I push the button for it to open. When a computer begins the boot process the motherboard initiates the start up of the PSU.I've unplugged everything (HD, Optical drive, floppy, external ports, etc.
