I checked the voltage at a drive connector and it read +4.9V while the 
system was running.

Well, I swapped the power supplies between my Linux router and the PC 
I'm on now.  Everything is now working without any problems.

Here are some interesting pictures.  (I cleaned the connector on the 
mobo with a small screw driver.)  http://www.dpagin.net/paul/atx-charred/

One thing bugs me.  The original PSU is 350W.  My test PSU is only 250W 
and it's working without even getting hot.  So, I could have gotten the 
Antec TruePower 330W instead of the 380W and saved $18.  That makes me 
wonder how much power is actually needed.
