  • If it was unexpected (by the operating system) there have been an event written to the system event log.

    What makes you suspect high disk I/O?  That is a rather rare case.  More probable is a problem with a device driver.

    As Dave suggested, spend some more time looking at the event logs for any events that occurred around the time of the reboot.  Unless you have disabled the specific event, an event is always logged to the system event log when a system is rebooted.  Take that time stamp and look for any anomalies that occurred shortly before that.

    Check your hardware logs. Servers from HP and Dell (maybe others) have a feature that HP calls ASR. This is where the BIOS detects that the OS is hung and not responding. The BIOS reboots the server to get it back online.
