Hello everyone, I just bought my friends old setup he just stopped using and put most parts in my tower. I got a xfx Radeon r9 390x , ASRock z97 ex4 , and a i5-4690k off of him. Everything works fine except the GPU. The motherboard slot works with my old gpu. I had Nvidia before but I have since tried: fresh windows install, resetting bios, flashing bios, checked connections, reseated the GPU, tried running only the GPU connected(black screen) . After all this I would jump to the conclusion of the GPU being bad but the fans work on it. Just doesn't say it's there in the slot.
