I am trying to build my own mining rig. For the moment I am struggling with one graphic card. When I boot the computer on the intern chipset with my graphic card unplugged, everything works fine and my OS launches. However, when I plug the graphic card, it shows the boot screen but I can't access to the bios menu despite pressing F2 and then... it is black screen.
This is my first build, could you help me please?
