It would be easy to add a watchdog timer chip like
this.
This chip monitors a pulsing signal. If the pulses stop (for a length of time determined by a capacitor value) the watchdog output pin of the part changes state.
The watchdog output could control a relay powering the computer. If the computer doesn't manage to shut itself down in lets say 10 seconds. The watchdog chip goes ahead and cuts power anyway.
I don't know about you, but I wouldn't want to count on anything involving Microsoft when it comes to the life of my CPU.
