PSU gone bad ?

Does this sound like my PSU went out to lunch ? Had my folding rig going 24/7 when I got up the PC wasn't running. Hit the switch nothing. Put in another mobo hit the switch and the HSF
tried to start turning and then nothing dead. It's a cheap Codegen 350 that came with the case.

Yep, I was going to say either PSU or mobo and you've already tried the mobo. Try a different PSU and see what happens.

I just hope it didn't fry my Epox board or anything else. I don't have another PSU to try. I have one on order but that was for another rig I'm putting together. Guess I know now that Codegen and epox don't mix.
