Hi, I just bought a Sapphire RX480 8 GB and I get no signal input on my monitor while installing the official 16.6.2 Drivers. I waited for about 60 minutes and then restarted.
Since then I got a black screen on windows login screen (sound still works).
I uninstalled the drivers in safe mode which at least let me use the card with windows basic adapter.
I already tried reinstalling and redownloading the drivers with direct and automatic install.
I'm running Windows 10 Pro with an Intel i5-3570K on a MSI Z77A-G43 mainboard, 8 GB G.Skill RAM and a Thermaltake Berlin 630W.
