The light only indicates +5V standby is available. I can't figure out why you replaced the CPU, but you should disconnect all other components instead of replacing them. Have you tried a different PSU or at least used the paperclip test and verified that all voltages are within specs with a DVM? If the PSU is good, then check for buldged caps on the motherboard, but those motherboards had good quality caps.

Edit: Have you replaced the GPU just in case it's defective? You wrote taht it doesn't POST; does that mean that it powers up just fine?

Read my edit and let us know exactly what happens. Anything is displayed on the monitor?

No fans no hard drives spinning. You have eliminated everything (gpu, ram, cpu etc etc)
The only thing I can think of is a faulty cpu fan stopping the board from posting so as to protect the cpu. If there are no beeps from the speaker to warn you what the problem is, I think its worse than that he's Dead Jim.

Mine still POST with the fan not spinning or disconnected (as do my other motherboards). Look elsewhere like a faulty PSU or motherboard.
