I use a fma88x killer asrock mobo. With a6-6400k CPU. Bios 2.10. Everything connected powers right up. Mouse gets power, keyboard doesn't for son reason.... Connected a hdmi cable and all I get us a black screen. Test the monitor and hdmi cable both are good. Also tried out a vga connection still black screen . Help
