OK.  Not happy about it but at least is an answer and can narrow down 
what to work on.  Will still keep an eye out for possible other issues 
but yes, it does seem more like a Southbridge issue rather than 
something like a power supply one.  

And as it seems one cannot bypass the Southbridge that means one needs 
to replace the motherboard.  Start looking more intently for good buys 
on Intel-based boards and of course the accompanying CPU.  Any 
suggestions?

OK.  (Will do later when done messaging and a lock-up isn't going to be 
as much of a problem.)
