CPU - Intel core i5 8400 Retail 2.80 GHz socket 1151

Thanks for the additional info, reason it was needed was so that we could check that integrated graphics were an option, confirmed that they are using the above info, sorry to say that the fact that you get no display using the onboard graphics when the the GTX 1060 has been fully removed from the MB suggests that you may have a bad MB and possibly caused by a short circuit.

Couple of long shots, try reseating the RAM and trying only one stick at a time + pull the CMOS battery from the MB and leave it out for a while before replacing it back in the board, this will clear any possible bad MB settings in the BIOS that may be causing this.
