I have a PE2650 runnning Win2K/SP4 that randomly rebooted, without warning, without any BSOD, and without anything logged in OMSA. It didn't matter what was going on with the server- backups, network traffic, someone directly logged on- it just rebooted whenever it wanted. For about 2 months, it would reboot once per day, about once every 2 weeks. During the past few weeks, it would reboot every day, sometimes 2-3 times per day. This was extremely frustrating, as a server is no good to me if it will not stay powered on.
The Windows system event viewer only logged an error of "The previous system shutdown @ was unexpected." I reinstalled Windows, loaded SP4 again and again, fixed the Windows Time Service errors, updated firmware, etc. Nothing cured this particularly frustrating problem until I worked with Dell server support to get new power supplies. It took a little persuausion on my part to get these power supplies, since the Dell tech kept leaning towards sending me a motherboard only. However, I was able to send him text directly from a Dell moderator discussing the power supply as a reasonable solution to random reboot issues. Here is the link:

After this, I was able to get some new power supplies, and since then, all my problems are solved.
