Hello,
My Windows XP Pro machine has rebooted twice in the last few hours for
no reason that I can see.
How can I investigate this?
1. Turn off the automatic restart so you can get a Stop Error (blue screen).
Once you have the Stop Error, you can research it here:

To change the automatic restart, Control Panel>System>Advanced>Startup and
Recovery>Settings and under System Failure uncheck "Automatically Restart".
2. Look in Event Viewer for clues:
Start>Run>eventvwr.msc [enter]
3. Try and answer The First Question of Troubleshooting: what changed
between the time things worked and the time they didn't?
4. Make sure your hardware is good and your machine is not overheating.

That should give you some starting points.
