Had this rebooting problem before for a while and it drove me NUTZ!  Inst=
alled RedHat
and FreeBSD and both rebooted periodically.  Don't know if my solution wi=
ll help or not,
but what was causing my reboots was the system BIOS.  The options for Pow=
er Management
in the system BIOS should have some settings for the monitor as well as t=
he hard drive.
I was finding that the spinning down of the hard drive caused the machine=
 to reboot.  No
traces in any error logs or anything...

Hope that helps somebody...somewhere...  :)
