Many reasons are possible.
1) If you are talking a really loooooong time, you may have overflowed the "time since last boot" timer. (Not likely with XP or Vista. More possible with some versions of Unix/Linux. Really unlikely with a 64 bit OS)
2) There was a power glitch that didn't completely turn your system off but still got noticed by your hardware.
3) One of your "automatic update" software products is set to allow automatic reboot after software update maintenance.
4) You have a virus.
5) You have broken hardware or software.
This is not anywhere near a complete list.
