I am trying this out now but i cant get it to work.
Not sure if i am doing it right though.

I placed a copy of my sgminer folder in c:\miner
Inside it i made a new batch file called loop with:

loop

cd c:\miner
start powershell.exe c:\miner\start_sgminer.bat
TIMEOUT 3600
taskkill /im sgminer.exe /F >nul
taskkill /im powershell.exe /F >nul

goto loop

When i fire loop batch file up it would launch sgminer right ? and restart it in 60 minutes.
But all that happends is that the countdown starts without sgminer launches.

If i start sgminer first and the loop up after it will kill sgminer when the countdown ends but not start it up again.

What am i doing wrong here ?

EDIT. I found another solution that is working here: http://hardforum.com/showthread.php?t=1796598&page=74
