Reboot every 1 hour, 19 seconds

[Rodolfo Alcazar Portillo]

HELP!

On October 2, 10:00 we had a power outage (I turned my PC on at 17:00).
Since then, my Fedora9 is rebooting approx every hour and 19 seconds. 

- imklog is the first line every reboot:
# cat /var/log/messages*|grep "imklog" #
...
Sep 30 07:06:48 rodolfoap kernel: imklog 3.18.1, log source = /proc/kmsg started.
Sep 30 08:10:29 rodolfoap kernel: imklog 3.18.1, log source = /proc/kmsg started.

... (and so on)


No useful information before reboot:

- Could not be a crontab problem, since it reboots approx every 1:00:19, anyway, no crontab entries.
- atq is empty
- Can't find something on /var/logs


Where else can I look? Could it be a hardware problem????

HELP!
