For a christmas gift to myself I thought I'd upgrade my PC's ram from the included SK Hynix DDR4 8GB 2666mhz ram to the same type but 16GB. I first tried putting the new ram in the other 3 available slots, which just led to the PC saying I still had 8GB. After that I tried swapping the old ram for the new, which gets me to where I am now: the PC no longer shows any video and gets stuck on a loop while booting. (imgur video and closer look at the inside here) Since then no matter what RAM or combination I have in I get the same result. This was my first time doing something like this so any help would be much appreciated.
