Okay computer will turn on, no post, but HD and lights come on without power to the CPU plug in.

When I put the plug back in for the CPU power (4or6prong dont remember) on the MB it wont start at all.

Hope that makes sense.

I am thinking bad CPU. I have tried multiple power supplies already.

Is the CPU fan turning? I've had some MB's that won't power up if the CPU fan doesn't reach full speed. Also, it could be that the CPU is not seated properly, or that the RAM isn't seated properly.

Are there no POST beeps or lights that can give you a slight clue as to what is going on?
