So we have a 3 gpu (all AMD 400's) rig running W10 pro, works perfectly. When we plug in a new (used) rx 470 we bought online and reboot, no cards are recognized. The added card powers with light (asus), GPU warms, but it kills all the drivers. Nothing is seen by the device manager. Have to wipe and reload adrenaline for the original 3 amd cards to be seen again and get them back running. Anyone seen this before?
