I have recently bought new RX590 Sapphire 8GB to replace my, now defunct GTX 980TI.
I connected it, however when i turn on the PC it's just black screen. I tried with diffrent monitor. Same result.
I tried using HDMI cable and the default D-Sub with an adapter.
My motherboard is MSI X99A MPower, my power supply is Corsair RM650X 650W.
I tried the monitor with the diffrent PC and it works fine.
Also the PC seems to turn on fine because all the lights inside light up, also also i think Windows loads fine because the lights and both mouse and keyboard light up too.
Does anyone have any idea what could be the problem?
