So i was running along just added another GPU to my rig making 6 total. I was going fine for 4 days mining then one morning it stops. I restart my computer and my miner cant find gpu. I look in device manager and nothing. I tried a few things and nothing. I used ddu to uninstall drivers. I try to reinstall amd crimson blockchain drivers and it cant find a card to install the drivers. I reinstall windows 10 clean and still cant see cards in device manager. 3/6 have lights on telling me there is power but everything I try and windows cant recognize the cards. im wicked frustrated. Please help. I have amd rx 580s. mining ethereum.
