You would be hard pressed, I think, to get a P/S to cause smoke to come out of a
motherboard.  Could it be that smoke came out of a P/S part and now that doesn't
work?

What I would do is unplug the P/S from all the internal (to the PC) components
and measure the voltages delivered to the motherboard.  I'm sure you can find a
pin out for it on the 'net.  Check the P/S fan while you're at it - I saw a
failure of one of those cause flakiness but it didn't hurt anything.

Just a thought.

350W is almost certainly enough for this setup, especially if it is a solid PS.
