Hi ImnPaul
Your minidump files just indicate memory (RAM) corruption no specific driver is listed

Go to the support page for your PRIME B550M-A AC Motherboard on the manufacturers website, then from there, download and install the version of Chipset drivers they recommend and while there, check for any BIOS update that may need to be installed
Boot your PC into BIOS, if there is an XMP profile set on your RAM, set that to default, if you are overclocking your processor, disable that.

Wait to see if your system stabilizes, if not, the best option is to download the widely available free utility MemTest86, then run a full 4 pass scan with that to test your RAM for physical errors
