half an hour ago i upgraded my pc from a GTX 960 & I5-6400 to a GTX 1080 Gaming X and a I7-7700K and right now when i boot the computer up no monitors or keyboard ect. light up and it seems like theyre all dead, but the GTX is glowing and cpu is correctly inserted. does anyone know how to fix and why its happening?
