The best suggestion on the web for a temporary fix was to aim a hair
dryer at the power supply for a minute or two, and dozens of people
swore that it worked. After about a minute, the power supply LED went
from flashing to on and the system powered up normally, and stayed on.
Obviously that's not a permanent solution, but it does tell me that
it's some kind of thermal problem, and, more important, it's a power
supply problem.
It might be a thermal problem (needing to get up to a minimum
temperature to function), but it also might be drying out moisture
that's shorting out PS components, such as caps. Maybe bad caps were
used in this line of PSs. I've heard of motherboards being carefully
baked to drive out moisture, but that's probably only a short term fix.
Just to experiment, with winter and dry weather coming up, you might see
if you have less of a problem during dry winter weather than damp summer
weather. If so, it could be moisture in bad components. Either way,
you're going to end up replacing the PS before summer (unless you've
been keeping the computer in a dank basement, and could just move it to
a drier place).
