The dump from 1/6 indicates a problem with the nvidia video driver, and the one from 1/4 indicates a hardware problem:

===============================================================================
Section 2     : x86/x64 MCA
-------------------------------------------------------------------------------
Descriptor    @ fffffa8005b60138
Section       @ fffffa8005b60280
Offset        : 600
Length        : 264
Flags         : 0x00000000
Severity      : Fatal
Error         : Unknown (Proc 0 Bank 2)
  Status      : 0xb200000000010005

Given the WHEA error was "unknown" (that is *really* rare), that makes this a bit of a trial-and-error situation. I'd start with completely uninstalling the nvidia video driver, rebooting, and reinstalling, and if that doesn't help you'd want to swap out the video card with a known-good one as a test, and/or testing RAM to make sure it passes without errors (and probably in that order).
