it's actually a brand new PS. I had to steal the PS from this computer
for another more critical one whose PS up and died. Did some research
and found that the 500W Antec Basiq 500 was alleged to be a good one for
being modestly priced, so I bought one (the original PS was also an Antec,
350W, and it ran flawlessly for all those years). the trouble did appear
a while afterthat, so it could be something weird about the PS. I don't
have a 'scope to view the noise levels of the output, but at least the
voltages all look good on my DVM while under "normal" load.

the video card does have a fan, I'll have to look at it again--last
time I checked it was running fine. there are actually six fans in the
computer, and all were fine at last check.

little dirt in it--there's a filter on the intake in front (with a
120mm intake fan) that I cleaned while I had it apart to steal its
PS, and mopped up what other loose filth I could find. mostly, the
collection of cat fur on the input filter nicely blocked smaller bits
of dust from entering. :) It usually gets opened up and the fur cleaned
out twice a year, more or less.

                         While we were still sinners, 
                              Christ died for us.
