that can be enabled to ensure that the OS will perform a restart when a fatal error is
detected. After a very brief blue-screen the system will restart.

You   can   enable   this   setting   buy   going   to   the   “System   Properties”   dialog   box   and
choosing the “Advanced” tab. Once there choose the “Settings” button for the “Startup
and Recovery” section. This will open the “Startup and Recovery” dialog box. In this
dialog   box   under   “System   failure”   there   are   three   check   boxes   that   define   what
Windows   will  do  when   a  fatal  error   has  been  detected.   In  order  to  ensure  that  the
system restarts after a 'Watchdog ACPI Event” that is set to 'Restart', you must make
sure that the check box for the selection “Automatically restart” has been checked. If
this option is not selected then Windows will remain at a blue-screen after a 'Watchdog
ACPI Event”  that has been configured for  'Restart' has been generated.  Below is a
Windows screen-shot showing the proper configuration.
