HastyCT here with an update of my postings above 11/18/22 & 1/6/23: my problem seems to be fixed. I continued to research the error log of W11 "Event Viewer" (START right click), updating all 3rd party apps/drivers or deleting them. I kept updating W11 version per each notice from MS. I also ran PC hardware diagnostics on my Dell Inspiron 3910 (processor Intel i7-12700} that passed numerous times. Up to 1/6/23, incidence of PC freezes decreased but still got daily issues. New Years resolution to reset PC & reload W11 (with attendant pain of having to reload all my favorite 3rd party apps). On 1st boot, got my old enemy PC freeze, so not that version of W11 bad. On/about 1/20/23 received notice from Dell of a critical BIOS update & from MS release of version 22H2 of W11. In one "fell-swoop" I accomplished both updates & as of 2/1/23, have had no PC freezes (5 days of continuous 24 hour operation)!!! Can't say W11 or Dell BIOS update fixed the problem & time well tell if it is permanent. Good sign is that W11 "Event Viewer" error logs events are now virtually zero!
Hope this helps others & Best Regards.....Tom
