Default Strange reboots


I have a CentOS 5.0 running as a web server.

# uname -a
Linux hostnamehidden.net 2.6.18-53.1.14.el5 #1 SMP Wed Mar 5 11:37:38
EST 2008 x86_64 x86_64 x86_64 GNU/Linux

Every 59 minutes (maybe every hour) it reboots without any logs,
without any traces and unfortunately with breaking software raid.
After reboot dmesg does not have any strange entries.

I double-checked crons, any strange services, nothing suspicious.

I did "yum update" recently.

I went to Datacenter and waited before the monitor but during reboot I
did not see anything strange. I guess reboot is cold reboot.

I changed all system and cpu fans. Upgraded system powersupply with a
more powerful one. Placed server infront of air-conditioner.

Do you have any idea?
