Hello,
I have purchased 4x RX 580 cards one of them is RX 590 they are mining well individually each giving me 29+ Mh/s but when combined together they are working fine but whenever I run the miner it's crashes my computer and giving me the blue screen. I am super newbie to rig and mining so all help would be appreciated. I have just contacted a technical guy who have told me it's a settings issue and he also said this rig can not work on windows, I need Linux for that and charging me $250 for the setting on Linux. I never thought it could be that technical. I am pretty confused and spent all the money on the GFX.
I am also sharing screenshot please see to it and let me know if it helps!

Best Regards,
The technical guy isn't qualified or don't have experience about mining rigs, believe that, he said the setup won't run on windows and I'm running 8x RX580 8gb on windows 10 OS here with no issue at all, if your page file size if small the miner will crash, not every mining softwares warns people about page file size
