If you mean reboots, you could try something like
zgrep ' Command line: BOOT_IMAGE=' /var/log/syslog*
Alternatively, look into commands such as last(1), uptime(1),
utmpdump(1) or who(1).
If you mean power outages short enough to not cause the computer
to shut down or reboot, I suspect you'd need special hardware to
monitor the mains voltage and report variations to the computer.
I don't think your ordinary ATX power supply does that but lots
of UPS do.
