Question I got multiple BSOD after changing components

Hi, in the last 2 weeks I had a problem. I changed my motherboard and CPU (I had a Gigabyte B450M DS3H and a AMD Ryzen 5 2600) and now I have Asus Prime B450M-A II and a AMD Ryzen 5 3600 (second-hand).

I get BSOD every once an hour or if I start the pc and then I start 3-4 apps instantly. I don't now what is causing the problem, I tried this things to fix but no result:
-Reputting RAM in different slots 1-3 to 2-4 and changing them with eachother;
-Reinstall Windows (11);
-Update BIOS;
-Update every driver;
-Disconnect the second SSD;
-Check RAM with MemTest86 and found NO ERRORS;
-Check both SSDs with Crystal Disk Info and NO ERRORS;
-Reput the GPU into slot;
-Deactivate XMP;
-Reset every voltage to RAM or CPU;
-No temps Problem;
-Deactivate Hibernation and Fast Startup;

I also want to mention that my games or apps crash often and that my pc freezes and crashes out of nowhere.

What can be the problem? I tried to search everything on google and couldn't find;

Probably the used CPU.

Probably the used CPU.

So, I should try to use another CPU and see if the problem still there?

Definitely worth the time IMO.
