Here's a picture of what happens when I try to install 16.12.2 on my system: https://twitter.com/TVsBen/status/811339203841839104
The same thing happened with 16.12.1. This time the AMD software cleaner put my system in a state where I could at least try installing the driver again, and it seemed to take.
Here's the hardware, same as last time:
16GB Crucial Ballistix DDR3-1600
Asus Strix RX 470 4GB
Seasonic 620W S12II
EQD Auria 27" IPS display connected via DL-DVI
Running Windows 10 Pro release branch (no insider branch at all) with all updates including Anniversary Update and whatever is on Windows Update for the system.
Also, the Diablo 3 issue I reported in my previous thread (Diablo III + ReLive = black screen ) is still there. Crashes after around 8-10 minutes in the game. Reverted to 16.11.5 again and again all is well. Super disappointed in this new graphics card. Reverting to older software fixes it so I doubt it's the card failing.
