Did you try the old PSU again?

 

[Originality]

Just to ask a potentially obvious question... did you make sure you flipped the switch on the back of the PSU?

Edit: I reread the OP and realised the lights go on and off. That implies there may be a short somewhere or insufficient power somewhere that's stopping the motherboard giving the "power ok" signal to the PSU.

Turn off after 3-5 seconds with no post(picture on monitor)?
You should take the cpu out, check pins in the socket
Had same problem ling time ago.
