Could be a hardware issue. Anything noteworthy in Event log?
Having a XP related problem. My computer has constantly been rebooting itself. No blue screen of death, no error messages, no nothing. Just stops what ever it's doing and goes into reboot mode. Usually when this happens, it will keep keep doing over and over again. Sometimes I get to login,, sometimes I don't even get as far as the Windows XP menu. It varies.
I've tried Safe mode. Sometimes it works and I can login in, but other times it even reboots in safe mode.
Think it might be a drive issue. Happened before so I erased and reformatted the drive and reinstalled everything when something similar happened late last year.. Things worked fine again until a couple of days ago. Not sure what went wrong. Tried to open another window and then it just started again. Computer sometimes sounds like a engine that's reving.
Got on for a few hours yesterday and no problems but once again tried to run two programs at once at the computer went reboot whacky again. The first time it happened two days ago I went in to safe mode and did a scan disk check. No problems. Came back later things were fine. Tried the same trick yesterday but didn't work this time. XP says the disc is fine so nt sure.
