Your minidumps only mention the driver "nvlddmkm.sys" as the cause of the crashes. This driver belongs to your Nvidia graphics card.
When you reinstalled the Nvidia driver, you downloaded the driver from the Nvidia website?
Before reinstalling the Nvidia driver, did you use the free DDU tool to remove the previous driver?
This ensures a clean installation of the driver and may fix some issues.
If you didn't use DDU, use it to remove the current driver, download the latest driver from the Nvidia website and reinstall it.
DDU: https://www.guru3d.com/files-details/display-dr...
Nvidia driver download: https://www.nvidia.com/Download/index.aspx
Run the downloaded file and follow the on-screen instructions to install the driver.
See if the system will work stable after this.
If you need a tutorial for using DDU, I recommend the video below.
