Have a Compaq 2.4ghz, 256mb ram XP-Home. Have 6 profiles configured. Shortly after startup, on 3 of the profiles, XP reboots. No warning is given. After reboot, a message is displayed stating a serious error, then takes me to a webpage defining driver problems. I have run virus checker: All OK. Ran Spybot: Cleaned out the junk. Ran defrag: looks good. Checked for mydoom a & b. nothing... Can't seem to find why 3 of the profiles will reboot soon after startup, while the other profiles run fine. Also, things started happening after one user was researching profiles on AOL. Also seems to crash/reboot while playing some online games. Ideas??!!
