Hi Dimitrios
Your minidump files just indicate memory (RAM) corruption no specific driver or other cause is listed
1
All drivers and BIOS on your B450 GAMING PLUS MAX (MS-7B86) motherboard are fully up to date.
2
You have performed most the required troubleshooting steps already.
Boot your PC into BIOS, if there is an XMP profile set on your RAM, turn that off, set it to default, or if you are overclocking your CPU, turn that off, then wait to see if your system is stable.

If not, because you have already re-installed Windows and tested your RAM and the BSOD's still occur, I think you may have a hardware problem and it would be best to take your PC to the Repair Center to have you hardware tested on a bench.
