So I’ve had my ryzen 5 3600 for a year and 3 months roughly and I’ve been getting blue screen error for multiple things like memory management and got one for kernel data in app page error I’ve tried a different mobo and about to change ram but I have a feeling it may be the cpu with it being different errors
Since you got a Memory management error it might be one of your RAM memory has gone bad or is going bad.
I suggest your run either Windows Memory Diagnostic or MEMTEST86 (Best method) to physically check your RAM Memory to see if any are going bad.
Also run in a elevated Command Prompt, SFC /scannow, to check your Windows OS and also run CHKDSK /r/x/f to check your Windows Drive for bad sectors.
As for your Ryzen 5 3600 if you purchased that processor and it came in a Official AMD Retail Box then you have a 3 year AMD Warranty on it and you can open a Warranty Ticket from here: https://www.amd.com/en/support/kb/warranty-information/rma-form
