what are specs of the PC?
updated drivers/bios?
Spec would be:
GPU: 3080 FE
CPU: i9 10900k
MB: MSI Z490 Unify
RAM: 32GB 3600MHz Patriot Viper
PSU: NZXT c850, 850watt
Drives: 1TB WD blue, 500GB Samsung Evo, 256GB Kingston (boot)
Funny thing about the drivers and BIOS, I actually updated my BIOS the same day as I did the update, as I had been putting it off and figured I'd use the down time to go ahead and get it over with. I was considering that it could have been the cause, but I figured reverting the windows update would be quicker to test, and it turned out to be the (or at least a) solution. Part of my troubleshooting did involve updating my drivers though, GPU drivers I always keep up to date, so I began with audio drivers as I recently switched from a USB headset to one that uses a jack. Disabled the Nvidia audio drivers as well, in case the realtek drivers and Nvidia audio drivers weren't getting along. I did the windows update then updated the BIOS since any shutdown or restart would have initiated the windows update regardless.
I did try troubleshooting windows and some other things as well. Used DISM and sfc /scannow to check for windows, I did check disk and made sure my drives were healthy, I did the windows memory test which passed, but here is a kicker. The crash was a complete lockup of my system and was the same every time, event viewer never gave any errors besides the unexpected shutdown as I had to kill the power to the PC every time essentially.. BUT one single crash did happen where I got a BSOD which gave the error code of "CLOCK_WATCHDOG_TIMEOUT" which upon looking into could indicate everything from RAM to CPU to drivers and windows misbehaving. This is why I did the RAM test, it also reinforced the fact that I was concerned about it being hardware related as the crashes were more common when the system was under load, but still would crash when essentially idle as well.
However, most of my hardware except my drives are brand new, as in less than a year of use. Going back a version on windows was immediately noticeable as a solution as my system would go at most 2 hours before freezing again, now it's been over 2 days with no problems. Sometimes the crashes were less than 5-10 minutes apart as well.
Also the version I turned back to is KB5009566, seems I went back quite a bit more than I intended, however, the crashes began the day of the update.
