You know vista and 7 "mostly" automatically restart if a major problem occurs to avoid damage... so try this,
Right Click "my computer", and select Properties.
Open "Advanced System Settings."
If prompted, click on "continue".
Open the "Advanced" tab.
Under "Startup and Recovery" click on "Settings"
Uncheck "Automatically Restart".
Doesn't do much but it might just give you enough time to figure out what went wrong instead of your pc restarting....
