You may have other issues on the box that may be causing this. A good
starting point would be to:
1. Update all the drivers on the system to their latest versions. Also
update your BIOS to the latest version as well.
The MPS reporting tool will tell you what versions of drivers you are
running on the box (check out the pstat and drivers .txt files):
Description of the Microsoft Platform Support Reporting Utility (816819)
http://support.microsoft.com/default.aspx?scid=KB;EN-US;816819
(run up the MPSRPT_SETUPPerf version)
2. then investigate the behaviour of the system.
3. If they are just hard reboots (i.e. no blue screen or crashes), then
maybe your system is infected with something or it may have a hardware
issue.
Cheers,
