Same symptoms as before, when I tried to run AQUA ROQS WUs a month ago. It runs for a few minutes, and then shuts the computer down. Just a hard shutdown, computer goes off. Have to power back on with the power button.

Other projects are PG on the CUDA GPUs only, and WuProp. I will probably add FreeHal back in too, eventually.
It was belting out RNA World WUs perfect, and I just switched back to Primaboinca, and that is running perfect too.
So....something about AQUA ROQS and the DrPop rig no-like.
