I submitted this issue to Microsoft Community and posted my Minidump and Sysinfo files are here. There are only two from almost a month ago, although I have had several crashes since then. These are probably from around the time when I actually got the blue screen identifying it as a WATCHDOG error. Recent crashes have not had a blue screen, the screen freezes and then goes black and the laptop restarts.
An advisor said, "Both of the minidump files only pointed to a system kernel driver "ntkrnlmp.exe" but one of the minidumps indicates "PROCESS_NAME: NortonSecurity.exe". I will recommend that you update or uninstall the Norton Security Antivirus."
Hopefully there is a better solution.
When this happens I have several Chrome windows open, MS Word, Zoom, and using a bluetooth headset and the laptop built-in camera. I have an external monitor, HP s2216h, Plugable USB 3.0 docking station. NVIDIA drivers were updated yesterday.
