My XP Pro will auto restart every time I try to shut it down. So my only recorse its to wait for the beginning of the restart and hold in the power switch till it stops..
Occasionally it will do a major fail may once or twice a day and say it has a fatal error, and totally reboot without warning.. I do not know it these are related.. I can live with the occasional reboot, but not with the restart..
It is a real pain when you go to shut down and it says updating do not turn off.. if you leave it for the update and go to bed of course when the update is done it will shut down then restart and when you get up in the morning its still running..
Does anyone have any ideas short of re-installing the operating system over the old... my understanding is that I can do that without loosing all my current setups..
A repair install might fix this, but I would bet against it. A clean install would probably fix it, but only if the fault is in the configuration rather than in a driver, etc.
I would start by ensuring the bios is uptodate, then I would check the drivers for video, sound, etc. are uptodate. Then I would uninstall all the rubbish that's probably hanging around. Finally, I'd make sure all security software was uptodate. And if that didn't fix it, I would uninstall all security software (whilst disconnected from the internet), and see if the problem persists.
This problem is unlikely to be caused by ordinary software (e.g. Dreamweaver) but is likely to be caused by a faulty driver or by software that ties into the operating system at a low level, such as security software (anti-virus or firewall) or perhaps a taskbar extension or something of that sort. It is also possible that a virus or spyware is to blame.
NOTE: If you are unsure how to update the bios, skip this since getting it wrong could kill your system.
