Bah, guessing wildly, most likely it is power -- a 2-3 second
dip in voltage can make the system reboot itself; a full
interruption in the supply is not required. Most short brownouts
are smoothed over the by the PSU, so they have been happening
without anybody noticing.

Guessing wildly, unlikely -- usually recent and not so recent
PCs have temperature related shutdown. Overheating might cause
a crash and reboot, but on my experience brownouts is more
likely.
