So i know this post is for Claymore miner, but i was having such issues, I moved to nicehash, does anyone else on here use nicehash with multiple gpus. It benchmarks all the algo's fine. When i go to start, it starts mining and then 20-30 min into mining the computer locks up. It doesn't turn off , or give any error message. It just locks , no mouse or keyboard. I have to then hard shut down the pc, and start mining over and it does it again. I don't know if it is certain algo's causing it or not, i tried most of them individually and it seems to do the same thing. I just want my rig mining already and i am having so many issues with the software configuration. any help is appreciated. Even if it is claymore code that will allow me to mine nicehash stratum links.
