Please check to see if your PC is producing any minidump files, I will check those to see if they provide any insight into a potential cause of the system crashes.

Open Windows File Explorer.

Navigate to C:\Windows\Minidump

Copy any minidump files onto your Desktop, then zip those up.

Upload the zip file to the Cloud (OneDrive... etc.), then choose to share those and get a share link.

Then post the link here to the zip file, so we can take a look for you.

    All your minidump files indicate that it is the device driver on your Nvidia graphics card that is causing the system to crash

    Completely remove the current Nvidia device driver using the widely available free DDU utility, then restart your PC and go to the Nvidia website to download and install a couple of slightly older version of the Nvidia device driver to try to find a version that is stable on your system.

    A slightly older version of that driver is more stable than the latest version.
