Day before error I downloaded and installed windows 10 1909 Update.
Note that pc left needing restart to finish this update.
Next day I did had few tabs openned and played videos, and one of them i tried switching to full screen and changing time of the video, than I get black out for few seconds, it was caused by two amd driver crashes.
It was novembar release 19.11.1 i think.
Yesterday i restarted and updated windows 10 1909, used ddu and installed 19.12.3 driver.
Than bsod occured once and amd driver crash every time in scenario explained above.
Im device manager Samsung TV was discovered as media device, and only main display was shown with full name under monitors (my Asus monitor).
Than after i wrote post before this, for some unknown reason to me, Windows 10 1909 decide to remove name of Asus under monitors in device manager, and showed it as generic pnp monitor, than suddenly in short time another generic pnp monitor showed in same place.
And now no above error, nor AMD crash.
Possibility is, as you said first crash occured by many tabs and many videos, or it could also be hanging windows update that needed restart.
And second one was because windows did not wanted to add tv as monitor in its registry or something like that, but suddenly it get smart by itself, and i remember it asking also once to restart to install some bus device, but the problem persisted after restart in time it asked the thing about bus needs restart to install.
However, right now no problem, just my both monitors are show as generic pnp monitors instead names in device manager, while in settings names are shown and also in amd settings i can see names.
This is mistery because i remember clicking scan for hardware changes in device manager, but windows still did not seen tv as monitor and rather as media device, until it sorted it out suddenly all alone.
So, ok, maybe we can blame windows for second time, under second circumstances, but what about first one with many tabs of videos?
Also I dont think I need furmark test, because i run cod mw, which stress GPU to 80c and 100% usage all the time, as well as other parts get big usage and temperature raise drasticaly, and i didnt experience any crash.
I play this game since i got pc, and i also played last night with 19.12.3 and all went fine too.
Why would amd crash on simple video and not under load of cod mw is really out of logic, but i think switching to full screen often is something amd dislike.
If you have any clues please do share them, because I would like to know what actually happened both of the times?
