I just replaced my ASUS P5K-E Wi-Fi motherboard and it won't power up. The green light on the motherboard comes on, but when I press the power button on the case, I just get a little squeak noise and nothing else happens. No fans, etc. I'm using the exact same components that I used with the original P5K-E that I RMAed due to Wi-Fi problems. Otherwise, the original rig worked fine and powered up every time. I checked connections and it seems that everything is connected properly. Any thoughts?
ASUS P5K-E Wont's Power Up

It sounds like something is shorting, and the power supply protection circuitry is shutting it down. Been through it a number of times.
1. Unplug everything that plugs in, including your RAM, vid card and any other plug in cards, and try again.
2. If that doesn't work remove the cards, unscrew the motherboard from the chassis and isolate it by sliding a piece of cardboard or plastic under it. Then, re-install your vid card and one stick of RAM, connect the power, and try to start it. You don't even need a hard drive for this test.
If it starts, you can turn it off as soon as it it gets past the point where it was failing. If it works under this condition, the problem is that something was shorting between the motherboard and the case.
If that was the problem, carefully re-install the motherboard with just a few screws (in case you have to take them out, again), plug in your vid card and one stick of RAM, and repeat the test to make sure it isn't shorting.
If that works, insert the rest of the screws, and try it again. The main thing is to test it along the way, and, if it fails after the next step, check to see if you can determine what caused the problem.
It could be something else, but that's what I'd check first.
Good luck.

Hi, Harvey,
Thank you for the reply and suggestion. I tried your 2nd suggestion, and still nothing. The light on the motherboard comes on when I plug the power supply into the wall outlet, and when I press the power button, there's a very quiet squeak. But no fans or nothing else. Is this an indication that it's the motherboard or the power supply? Or something else? Is there anything else I can do to try to isolate the problem?
Thanks.
