Also, double check any cables you plugged in or unplugged since it worked fine.
He already tried this, said so in the OP.

If it was working previously then it probably isn't a bad CPU.... Have you checked to make sure none of the pins in the CPU socket are broken? Also, I'm assuming you have tried using one memory module at a time, correct?

Otherwise, I would say it has to be a bad motherboard. You have knocked out every other logical answer if you do what I recommend above.
Yup. All pins for CPU look good. I've used one piece of RAM at a time. At least if it's the motherboard it has a warranty.

I don't think there is much of a question...

The CPU is fine
The RAM is fine
The PSU is fine
Nothing is shorting anything out
CMOS is cleared
All expansion cards, hard drives, dvd drives, etc.. have been removed

There is nothing left it could possibly be as far as I can see. Good luck with your RMA.

Alright. I'm trying to figure out whether to call Newegg or Gigabyte, and dreading talking to tech support. But I will. Thanks for all the help everyone. Looks like a really helpful forum.

So out of curiosity, is there something I could have done that would cause this to happen? It's not the first motherboard that stopped working while I was working on it, and I couldn't figure out what I could have done. Is there anything that commonly breaks on the motherboard? Any way to tell?

Thanks for the help guys. I just got my motherboard back from Gigabyte and tested it. Now I have a new problem with it. I would really appreciate any input.

It seems to start up completely normal except there is nothing on the screen. I don't know if it used to, but the fan on the graphics card isn't spinning.
