When you took your computer to the shop did they RESET the BIOS or did they UPDATE the BIOS?
What version of the system BIOS are you using?
The Asus Prime A320M-K motherboard requires BIOS versions 3203 or higher to run the Ryzen 3 2200G processor.
Also: Is the RAM you are using listed on the QVL for the processor you are using?
When i bought pc BIOS version was updated to 3208 i think or 38.. something and it worked well. In shop they reset bios and updated to 4023 the latest one. RAM is listed there. Is there some possibility that HDD made this problem because it has almost 1000 days of working ad 100% health and performance like i said?
