Question Repeated BSODs on my friend's (and now mine as well) CPU

[DanNotC(h)ristian]

Hello there,so my friend has had this problem since the very first month he has gotten his PC (and i've gotten mine as well), where he gets random, constant BSODs, sometimes once a week, sometimes more times a day. We both have the same exact PC basically. Here are the specs:
-Mobo: AsRock B450 Pro 4 (with the latest Bios version)
-CPU: AMD Ryzen 5 3600
-Cooler: Stock (his), Cooler Master Hyper 212 RGB (mine meanwhile)
-RAM: GSkill Aegis 16GB 3200 MHz (mine has 32 GB in the meantime)
-GPU: Ganiward Ghost NVidia GeForce RTX 2060
-PSU: Seasonic S12 III 550W
-Case: Kolink Observatory mesh lite / similar.

So my friend has had this problem from the very beginning, while i never encountered it before, and so we started troubleshooting to see if we can find it ourselves and never actually managed to do so until a few months ago where he got a CPU related error followed by a BSOD, and since he moved closer to me and we were actually able to meet irl i asked him to bring me his PC over so i can take a look at it closer because it has gotten to the point where he could not start his PC anymore.As he came over the first thing i tried was to swap out his ram with 2 sticks from mine, to see if it was maybe ram related, but since it apparently wasnt, i decided to swap our CPUs to see if it acted any differently and it did. So i ran some Cinebench on both of the PCs and they seemed to be stable at first.I let him take my CPU for the time being to see if any change would find place and i noticed my PC started getting those random BSODs now (another problem was the youtube site getting the error ''oh snap'' whenever watching a video). so i started playing around with the CPU for a bit, like undervolting, setting the power plan to only 99% so the CPU won't boost anymore, deactivating the XMP Profile in BIOS, etc. I had to do all this myself since my friend never really knew much about PCs and was kinda afraid to start playing around with stuff like that. Nothing really helped, but what i noticed was that i am only getting them like once/twice a week, three times at max.So at first i tought maybe he only had bad luck at the silocone lottery since my CPU seemed to be running completly fine in his PC. UNTIL 3 DAYS AGO where he started getting those BSODs again, on a daily basis ever since, and now i'm completly out of ideas, other than the motherboard being the problem and slowly frying the CPU. I have no other option left but to try and ask reddit about this problem, hoping that someone could help me fix it. Thanks in advance.

I take it those zip files are both system specs. Can you post on imgur or something. I'm not comfortable downloading and opening a random zip file.

They are dump files of the crashes, i uploaded them on a site recommended by reddit after pulling them out of C:/Windows/Minidump so there should be nothing wrong with them.
