I can install either one of my three cards (MSI R9 280x. ASUS R9 280x and Gigabyte 7850) on either of the motherboards and they work just fine. Until I install the drivers that is. As soon as I install the drivers the MSI card just gives me a black screen as soon as I login into windows. And the other two cards show green dots all over the screen. This happens on two different motherboards with two separate installations of the OS (both SSDs, if that matter). This started happening with the 18.8.1
What can I do? Is there some software settings I can change?
