What a few days. My Windows XP install on the Dell has been unstable for a few months; and I thought I had managed to recover XP enough to have a stable platform. Unfortunately, on Friday night it finally exploded. Also two Outlook .pst files went west (thank goodness for backups!). Completely erased the hard drive, reinstalled XP, and all the required updates. Sometime between installing these updates and the virus checker, I was infected with a ping-flooding virus. All is cool now. Just recovering the final pieces now.
