I have the same problem with the Sapphire Radeon RX 590 NITRO + Special Edition. The drivers went out during the upgrade. Now the card is not working and I can not install any drivers.
Happens the same to me the same error and blue screens after a clean installation. I normally play apex Legends and after i tried to install the new version 19.7.1 im constantly having crashes in game. I already installed the previous version 19.6.3, but i Still have crashes sometimes but less.
Ever since I installed 19.7.1... my 3 monitor setup started flickering and artifacting like crazy... Why am i experiencing this problem after installing the latest beta?
