Thank for your response.
It doesn’t matter whether the BIOS is in default settings or in adjusted settings, I’m getting the black screens either way.
Mainboard BIOS was updated untill the 12th of October 2015, going to update my BIOS with the latest patch now and i’m going to do it with just one screen attached. Don’t really know why I should do this since the GPU should be able to handle 2 screens with ease. Besides I really need 2 :D.
I have checked my memory several times and let the tests run for hours and hours , the results were the same no errors in the memory.
