It looks like the issue might be with your GPU. Check the settings you were using, along with the game you played. Make sure all chipset drivers and BIOS updates are installed. See how much power your CPU and GPU consume during games—use MSI Afterburner and Rivatuner for details. A screenshot of the stats while gaming would be useful.
What is this old CPU? If it's another, older Ryzen chip and you are on the same motherboard, did you update your BIOS and chipset drivers after the install?
The B550 Gaming Plus isn't compatible with Ryzen 2000 series processors. Were you using another motherboard? Did you transfer storage devices (especially your operating system drive) from a previous setup if applicable? Have you updated the BIOS and are you using the most recent chipset drivers?
You would determine the GPU as the problem by observing performance issues, slowdowns, or errors that occur specifically when using the GPU.
