We have a computer that will restart approximately 6-7 times each time it is turned on. Some times it will get past the Login screen before it restarts and sometimes it won’t. Once it gets going correctly it is fine. It does not restart unexpectedly after the first thing in the morning. If we choose to restart the machine in the middle of the day it will start all over again. It does not appear to be a morning only problem. The computer is a 1 GHz possessor w/ 256 MB Ram running Win 2000 Pro.
