Quick specs:
Ryzen 5 3600
ASUS TUF Gaming B450M-Pro II
8x2 3200 MHz Kingston Fury Beast RAM
Galax GTX 1650 Super
Crucial P2 1TB SSD
Corsair CV 650
Windows 10 Home
BIOS 3810 (2022)

Okay, so before all of this inconsistent posting, here's a sign that I think lead to the current issue I have:
Whenever I will boot from a cold shutdown, the PC will boot like normal and go to Windows and to the Login screen, after I put my PIN it will then go to a black screen, stuck there (Cannot do any mouse movement or anything). What I have to do is to hard restart it and then I can proceed to the desktop like normal now, NO issues after the 2nd boot, until I do another shutdown that'll open the PC after one night of sleep. This went on for about a week.

2 days ago, I thought it'll be a graphics driver issue because I upgraded from a 1050 (blamed drivers because it boots normally to Windows, just after the login is the problem) so I DDU'd it, installed, booted up without the black screen issue, went on about my day and now shut it down.

LEGEND: W = working RAM stick, D = defective RAM stick

The next day, when I boot up the PC from a cold shutdown, it did the same thing, and on the 2nd boot, it now refuses to POST, no display. I tinkered RAM configurations first and lo and behold, I can post on W on 3rd slot, so okay I used the system like normal then shutdown for the next day.

The next day which is today, W apparently doesn't post anymore on the 3rd slot so I tinkered W again on other slots (FAIL), also tried D on all 4 slots (FAIL), cleared the CMOS (FAIL). Now I'm getting a bit desperate, I have a Ryzen 5 2600 lying around so I switched to that and now W posts on all 4 slots, also still tried D on all 4 slots (FAIL), you can't blame me but think that my 3600 is now dead because a different CPU is POSTing properly with W. So to rule that out, I switched back to my 3600 and now W posts on ALL 4 SLOTS, D still fails on all 4 slots lol.

Now the question here is, I know that D is now guaranteed defective, but why would switching CPUs make W now post to which it failed before, is it because of the reseating of the CPU that fixed it? (Checked pins of both CPUs, they're perfect).

Why does dead RAM sticks have such high affinity to Ryzen CPUs? (Know a few friends of mine that also have RAM-related issues to their Ryzen systems)

I will update this thread (probably) if I get any more issues with POSTing after a cold shutdown, I might also not shutdown my PC for the meantime until I finish all my important things

I will also probably do a BIOS update (still thinking about it), do you think that can maybe help revive D stick? (doubt)

Also enabled DOCP on W, it works fine.

EDIT: T-Force 8x2 3600 MHz RAM just arrived, PC is now back to 16 GB, did NOT update BIOS.

update to BIOS Version 4631
maybe incompatibility issue
I have now updated to BIOS 4631 for peace of mind, although temps are still high on my 3600 (idle on 50-60 and 70-80 on gaming) and upon further research, it seems it's really normal for Ryzen 3000 (another "issue" I want to deal with). Seems to me a stock cooler and case issue.
