Inspect the capacitors.

Apparently there were some bad Nichicons, which would normally be
a good brand of capacitor. Most of the time, it's other (fly-by-night)
brands that fail prematurely. Nichicon is what you use when you need
a replacement.

Hi Paul,

I looked at every electroylitic capacitor for a bulge (even slight) and
I did not see one. Note: I once had this, no boot up problem, with my
NEC desktop computer and found some bad caps (bulged). After
replacing them, all was "well" again.

I did not measure or check ESR of any caps yet.

Thanks for your tip, John
