I bought a parted out 9400f off of Facebook (the 9400f has no igpu). It is with the original HP Pavilion motherboard and case. I put in a 1060ti (originally appears to have a 1660ti) and cannot get it to display anything. Sounds like a somewhat common problem with HP. What is the best way to work around? Anyway to get into bios using a laptop or over lan? Update bios without seeing anything? Thank you so much
