@MK2boogaloo maybe you need to switch something around in the bios
@MK2boogaloo you might need to switch the video output to the gpu, at least for during boot. do you have on board gpu? if yes, you might connect to that, boot and then look around if the new card is detected?
@MK2boogaloo with on board graphics as well?
I'm using Arch so it might be driver related issue?
