Hi any suggestion to make the miner more stable on Win10?

it runs from a few minutes to a few hours and then I am not sure what happens as there is no log file to check, but when I come back I found my computer rebooted and mkx miner off.

Can this depend on where I mine as well? Is this supposed to still be used only for NiceHash?

I am currently using it on a pool.

I am now trying running with intensity at 22, but don't feel like that's a solution, I am getting several Mh/s less than optimal.

Any help? Thanks
