Perfectly normal - ignore.

Thank you very much. Still trying to track down why my machine random reboots, trying to fix and understand any error I see. I recently also observed the machine reboot when the screen saver comes on, so I turned that off. Still testing, and trying to find a free day of time to try a reinstall. Thank you again.
