error 24 is not in the BIOS q code table of the user manual found here https://dlcdnets.asus.com/pub/ASUS/mb/SocketAM4/ROG_CROSSHAIR-VII-HERO/E13835_ROG_CROSSHAIR_VII_HERO... page number appendix A-1
I think that might be showing your CPU temp as 24c
It sound like a memory error,
Check that your memory is inserted correctly and the retainer brackets are clicked into place,

Just watched your video again, make sure you have 2 sticks plugged in to DIMM SLOT 2 and SLOT 4 like this diagram

have you checked that your running at default memory settings in the BIOS, 2133mhz is default.

Whats the model number of your ram ? is it on the QVL list ?
