Rayzore,
You were right, the system was obsolete. I went ahead and upgraded to an MSI K7N2 w/an AMD 2500 CPU and the problem went away and has not come back. I subsequently had a brand spanking new video problem, but downgrading to a less recent driver fixed that. ;-)
Thanks guys for all the sound advice, I guess sometimes the answer to the problem is to throw it away and buy a new set of problems.
