Installed any 3th party printer drivers? Or other 3th party
software, just before this problem started?
To get more information, I would configure the server to *not*
automatically reboot when a critical STOP error occurs (in Control
Panel - System). Next time it crashes, it will show you a Blue
Screen of Death. Write down the STOP error code, the parameters,
and possibly the name of the driver causing the STOP error.
Either post this information here, or check the troubleshooting
tools for this particular STOP error in the
MSDN Bug Check Codes pages at
