Mystery Reboot, Win XP sp2

[Alley Cat]

I am running Win XP sp2 (Media Center Edition/repackaged XP Pro)

I have Zonealarm firewall, XP firewall disabled. Automatic Update was set to "Notify me, but do not download", now completely disabled in Services.

I want to know why my computer rebooted itself. I looked at Event Viewer, no errors found.

How can I find out if there was another stealth update from evil microsoft, or a normal update, but if so, it is not suppose to download itself and reboot.

How can I find out why my computer rebooted itself ?

Microsoft can't do that. I have mine set to that and all is well.

The most likely cause I can think of is the CPU has reached a high temperature and the PC has rebooted.

Happened to me once when I took this green thing off my fan (which makes it cool only the CPU).

It could quite possibly be power related! Is your PC on a UPS? The PC's power supply could also have had a hiccup? Perhaps a glitch in the power could have caused the reboot; sometimes the event viewer will not record something like this.

If it only happened once don't worry about it. Still, you should go to System Properties - Advanced - Startup & Recovery Settings and uncheck "Automatically Restart".
