when did this start? Had you just added/removed any hardware/software? How long does it run before this happens? Will it start up again immediately after shut off? Have you had one or more problems recently that have been getting worse - if so, what?
Sometimes when it starts up it will stay on for a few minutes and will restart itself. Othertimes you have to restart the computer and it might stay on and might not. I just added the windows xp sp3 download and it seems to be working so far. This is what I downloaded. WindowsXP-KB936929-SP3-x86-ENU.exe
