I have a similar setup: ab350 pro4 (with beta bios 4,73); 8x4gb g.skill ripjaws 5 3200 ram; also a sony 40" or 42" TV through HDMI; cougar 550w.
I'm having some trouble with the video_tdr bsod, and I have also seen, the "crash" you show in the link, but my pc doesn't restarts after that, actually that happens (if its the same thing) when I go full screen in games or even browsing (F11, full screen youtube video). The weird thing for me is that this doesn't occurs while using internet explorer.
This thing happens on every game (fortnite, pubg, LoL) except WoW (Wotlk version). But it has something to do with full screen fullscreen windowed works fine.
Maybe it's a similar issue.
Also regarding the bsod, watched a yt video saying that setting the primary video to IGP might solve the problem to some extent. I was not getting this kind of bsod with the old 4.60 BIOS, but since I was trying to OC a lil bit was getting many freezes and BSOD and moved many things in BIOS cleared cmos a couple times. The thing is in the 4.60 there was an auto option for primary video adapter, at least in 4.73 there is no auto option, and when I checked it was set to EGP (or something like that), changed to IGP and played a pubg match, lets say 15-20 minutes or so and everything worked well (this was like 2 hours ago). Still don't know it this fixed the problem yet. I'll update when I have chance to use my pc a lil bit more (@work rignt now :c).
Hope it works!.
