Done. I edited some parts that I thought weren't important and contrained information I don't want to upload to the internez. Sorry about my paranoya. Let me know if you need some of the censored data and thanks for the help.
The graphics drivers are from Feb 2017. Time to update.
Wow I feel so stupid now. All I had to do was update BOTH GPU drivers *facepalm*
Seems like the outdated intel GPU drivers were the issue. Thanks!
(I updated them via the device manager, which might have been a bad idea, but when I tried using the newest one on the intel website, it wouldn't install as I got an error that the driver has not been validated for my PC)
there is nothing personal in a dxdiag log, post the whole log un-edited, and just because you thing its not important, doesn't mean its something thats not needed
The DxDiag can reveal my country and my PC name, which I would like to avoid sharing. And I know that the issue was caused by the GPU(s), so I reckon information on my sound/camera/etc devices will not contribute to the problem here, and the less I share the better I feel, even if it is unreasonable. The sound device in my case would also reveal information about my country.
