Bryan and Aaron,

You each get an "A" on this test. I just replaced the power supply
(thanks very much, Steve) and everything is back running at full
throttle. It's going to be a pleasure sending Dad's computer back to him
without having had to touch his Win2K system. Of course, he *will* be
getting a CD/DVD+/-RW drive upgrade and an additional 256MB of RAM. Just
the kinds of toys a 91-year-old kid will appreciate.
