I have the following situations with my 2 rigs:

Rig 1: 2 R9 390, 1 R9 Fury, 2 GTX 1070, 1 GTX 1060, only recognize AMD platform, and mine good. Windows 10 Pro 1709 Blockchain Driver AMD, and Geforce 391.35 nvidia GPUs.

Rig 2: 3 RX 580, 1 RX 480, 1 RX 570, 1 R9 290, miner closes and restarts in a infinite bucle, sometimes the rig crashes. Windows 10 Pro 1709 Blockchain Driver. GPUs are NOT modded.

Any help thanks. I will update Geforce Drivers for Rig 1, it is so old, and try again.
