The problem began to occur a week ago out of the blue. It will boot into Windows after it reboots itself a few times; during the first few tries the system boots up to the loading screen then reboots itself. Finally after a few attempts it will succesfully present the XP logon/welcome screen.
This problem seems to occur when I’m starting up the system for the first time that day. Once it gets into windows, the system works fine indefinitely.
TIA
NOTE: Other than applying Windows Updates the computer has not had any major upgrades, nor software installed.
