Question My PC gets stuck when restarting and bios as well. Can't enter bios either ?

As the title says, my pc gets stuck in restart and in bios.
So I had an internet hickup, but might have been the pc itself. So I restarted the modem and meanwhile it was booting up again I decided to do "update and restart" so it installs the downloaded windows update meanwhile the modem boots completely. So I did that and "restarting" was stuck for like 10-20mins.

I decided to manually shutdown the pc and when I booted it up again the bios was stuck, no loading and remained there for another 10mins or so. I manually restarted the pc and the same.

I decided to clear cmos, it kinda worked but the pc wouldn't post. So I checked the ram, I removed the 4th slot ram and the pc booted just fine.
Here is the thing, I removed the "working one" lets call it Ram1, and exchanged it for Ram2 in the same slot, and it worked as well. Then I removed Ram2 to then put Ram1 on slot 4 (which was empty) and it booted fine. I then tried Ram2 alone, in the same slot 4 and it worked as well.

So at this point both are working.

I placed both again in their original spots and it didnt boot, the dram and cpu white leds where turning on back and forth.

I swapped them and then the PC worked as normal.
Now with a working pc, I started playing Escape From Tarkov (ram intensive game, know to have memory leaks)

I played just fine, when the game doesnt feel stable or freezing I would usually close the game by ending the task .exe.

Now here is the odd part, I couldn't end the task at all, but it was taking very few resources on my pc. So I decided to again, restart my pc. And the same thing happened all over again.

Now Im running the pc with 1 stick, but as I tested previously, both work individually.

Gonna try reseating them again and see if they work together again.

Specs:
CPU: i7-8700k
GPU: RTX 3080
Mobo: Z390 Edge Gaming AC (or something like it, forgot the full name)
Ram: 3200 mhz 16gb (2x8gb)
PSU: 650w Gold

Any clues?

I did the tests again.

I'll be more organized.

Using only Slot 2 and 4 as I always have.

RAM 1 (the "good one") alone on Slot 2: Worked
RAM 2 alone in Slot 2: Worked
RAM 1 alone in Slot 4: Worked
RAM 2 alone in Slot 4: Worked.

RAM 1 in slot 2 and RAM 2 in slot 4 was the one the gave me the problem again when I restarted etc.

I swapped RAM 2 into slot 2 and RAM 1 into Slot 4: Worked
PC booted like normal. (Note this was the same swap I did before the problem happened again.

Did windows memory diagnostics tool for each stick and no problems.

Gonna try again with both in since it booted again like normal.

As a side idea, I think it might be an effect of playing the game not gonna lie. I'm not gonna play (I'll be busy anyways) and it would be my 7th or 8th wipe lmao. Anyhow, I'll update here if it happened again even if I haven't played it.


I know 16 gb is not enought for this game, I plan to upgrade soon so I might just have to wait. Though my build is from late 2019 when I built it. Maybe the ram is getting faulty or the mobo itself.

Edit: I wanted to add that I did a clean Win 10 os install about a month ago. I usually do this very 6 months.
