No. At the time, I had Win98 on there and was using it
for basic web surfing. I had very little installed.

The only things the compatability wizard complained about
were drivers (video, etc.) I did a fresh installation of
XP with freshly downloaded drivers (and have updated
since.) So other than a few minor programs (winamp, etc.)
there are no programs that were installed on both W98 and
XP on this system.

Since installing XP, it's become my main machine (it's not
fast enough to run the kid's games, so they took over the
fast one.)

So I do have a lot of stuff on here now that I didn't have
before.

I guess the only thing I can think of (since nobody seems
to know how to extend the shutdown flush cache delay) is
to wipe the C: partition, install XP fresh, re-activate,
and install one or two things at a time.

A lot of trouble. And I can't do it too many times
because of the activation. (I had heard that if you save
the wpa files, you can simply restore those if you re-
install, but a friend says he's tried that repeatedly and
they unequivocally do not work with sp1. They always get
rejected.)

I guess I can run it for a while without activating it,
but it's still going to be a lot of trouble tracking it
down. Especially if it turns out to not be an install
program causing the problem but just some quirk of my
hardware.

Thanks for the effort though. Oh well.
