Alright, there are some updates you need to apply.
Okay, there is a V2 version of your motherboard so double check its just the B550 Gaming X mobo and not the B550 Gaming X V2 mobo.
Then go to the manufacturer website of the mobo to get your chipset drivers: https://www.gigabyte.com/Motherboard/B550-GAMING-X-rev-10/support#support-dl-driver-chipset
If your comfortable doing so there are some BIOS updates availiable so you can update to the latest version, the updates include the AMD AGESA ComboV2 which is related to the controller, ram and CPU.
Then update your GPU driver here: https://www.nvidia.co.uk/Download/driverResults.aspx/187107/en-uk
Some of these driver may require you to restart your PC, so restart before updating another driver.
Check your windows updates also.
If this does not work lmk, It maybe a case of OS file repair which we can try later.
