Sounds like DDR4 not set correct to the motherboard and CPU, I think specifically CAD_BUS, hence I recommend you use Dram calculator and go through the official steps recommended by 1usmus = https://www.techpowerup.com/review/amd-ryzen-memory-tweaking-overclocking-guide/

Also the procODT is very important to get correct.

If both CAD_BUS and procODT are on botherline, then it will exactly happen as what you wrote, sometimes ON sometimes no ON. On some PCs it would beep warning 3 times then boot. Also a setting mismatch as CAD_BUS and procODT in bios. I think.

Welcome any other gurus to fill in the gaps.]]> Mon, 08 Jun 2020 15:29:47 +0000 https://forum.asrock.com/forum_posts.asp?TID=14601&PID=76231&title=sometimes-computer-doesnt-bootup#76231 https://forum.asrock.com/forum_posts.asp?TID=14601&PID=76219&title=sometimes-computer-doesnt-bootup#76219 Author: Squirrelville

it's been a little while since I was really in the game, but I have experienced issues like what you are describing. It was not like I ever specifically solved the problems, (like found that one bad setting or one bad part) I would disassemble the system clean everything and reassemble and stability would return. I would chalk it up to contacts that did not make consistent connections.

The most problematic (I feel like) spot is the memory contacts?

hope this helps

good luck with it
