ok, got a new motherboard (ASRock A785GM-LE) put in an older but previously functional (Phenom quad 9850). Got everything hooked up in the case, hit the power and it comes right on, for about 10 seconds then shuts down. Second time 3 seconds, shuts down. So I switched out the PSU's, same thing. Tried breadboarding, same thing.
The one thing I noticed was that it doesn't beep on start up. I'm getting complete silence which usually means the RAM is shorting out the PSU.
I'm at a loss. I've tried everything I know to do, done the step by step process of connecting one thing at a time. Anyone else have any theories as to what it could be?

Oh and it will stay running with the RAM out so I tried different RAM, first socket then the second socket, same results, powers down shortly after turning it on.

Maybe your memory isn't compatible.

It was the cpu, fried like a chicken. Amazing how parts can just stop working when all I did was remove it from one mb where it worked and installed it in another and it's now mysteriously fried.
