Try the command -r in your start.bat and create a file called reboot.bat with the command "shutdown /r /t 5 /f"

“
-r   Restart miner mode. "-r 0" (default) - restart miner if something wrong with GPU. "-r -1" - disable automatic restarting. -r >20 - restart miner if something
   wrong with GPU or by timer. For example, "-r 60" - restart miner every hour or when some GPU failed.
   "-r 1" closes miner and execute "reboot.bat" file ("reboot.bash" or "reboot.sh" for Linux version) in the miner directory (if exists) if some GPU failed.
   So you can create "reboot.bat" file and perform some actions, for example, reboot system if you put this line
"shutdown /r /t 5 /f"
