I would also guess overheating. But it also may be a BSOD.
[turn off automatic restart]
Right click "My Computer", choose "Properties".
Select the "Advanced" tab.
Under "Startup and Recovery" click "Settings".
UNselect "Automatically restart". Click "OK" twice.
This will help determine the error if it is a BSOD.
You can also check your error log:
Right click "My Computer".
Choose "Manage".
Expand "Event Viewer", click "System".
Look for an "Error" event on a day where it restarted, tell us what that is.
You might also check the "Application" log.
This all assuming you have XP of course. If not, never mind.
If you don't have XP, do this:
Throw your box away.
