I've been struggling to get my rig to work for two weeks. It was mining fine 24/7 for days at a time. Then it froze, and ever since then it'll mine for a minute, two cards will go to zero hash rate, and Windows freezes. Tried reinstalling drivers. Connecting them in various orders. No one card seems to be causing the problem. I'm at a loss here and this thing is sucking up all my time.
Win10, rx580s (one 480). 1000W evga psu. Biostar mobo
I've had rigs run for days or even weeks and then out of nowhere behave like that. Unplug all your sata cables from the psu and see if any of them are damaged/melted.
