He's already replaced C9...the "starter". Once he's getting the Beep, the 
PSU has already started and is 99% more than likely NOT the cause of the 
problem, same as Mikes.

It's going to be an issue on the main board. Apart from reseating ICs, or 
swapping socketed ICs out for good ones, it's time to break the scope out.

Mark.

It's possibly the same problem I mentioned in passing on another
