It could possibly be that the G.Skill RAM is not supported considering it has a maximum memory clock at 3600 MHz. Try the Kingston RAM and go back to the BIOS. See if it is clocked at its default settings. Disable the XMP for now. See if it solves the issue.

If not, try emailing the Asus support and they might give you a BETA bios that hopefully supports the RAM modules you now have.

Remove your components from the case. Put your motherboard on top of the cardboard box that it came in. Make sure your CPU, heatsink, memory and GPU are properly installed and all the necessary cables are connected. Also verify that you're not overtightening the screws for your heatsink. Start your system and report back your results.
