Hi there, I have just tried adding some DDR4 RAM to my custom built PC, and it just decided to not post. The PC itself turned on, all the fans engaged, however, the red LED for DRAM was lit up. I tried replacing all of the RAM I had in at the time, cross checking it with my motherboard manual, and going back to the original configuration, however, nothing has worked so far. Any and all help would be amazing. The only thing I can think of that would have damaged anything would have been when I took out the RAM, and I heard a slight clicking sound when I pulled out the ends. Is there any way to check for damage to the memory slots? Any and all help would be appreciated, thank you.
