How can I tell if it is my Mother Board or CPU causing the problem?

[ChristopherGillaspie]

I came home to a dead computer yesterday. I have stripped it down to just the mother board, power supply, and processor. I get no response whatsoever. Not even a soft power light. I have tried two other power supplies with no success. I now believe that either the mother board or the processor has failed. It is a Gigabyte EP-45 UD3P with an Intel Duo core processor.

I am wondering if there is any way to figure out which one is the problem.

Thanks,

-Chris

Easiest way is to swap the CPU with a known good one.

BTW, without a video card and RAM in the test mix, you won't get a boot...

No LEDs on = bad PSU or MB, one of which you believe to have eliminated as the problem.

No, but he will get beep codes. I can't rule out the CPU, but you will have 20 if not more Motherboards go bad before you will have a CPU go bad.
