Question Mining rig cards not being detected

[Brycen121]

With my mining rig, I have 8 1060 6gb, and at the moment only two are being detected. I have tried uninstalling my old drivers and installing new drivers from Nvidia (whenever I did my screen would stay black until I would shut it down {I let it remain in the black screen for well over a day}, and other times it would blue screen with the error "SYSTEM SERVICE EXCEPTION", factory reset on my computer, resetting my bios. I genuinely have no clue on what to do next. Thank you in advance for the help
