It is one of those bugs that makes you feel like pulling your hair out due to the amount of money spent. I actually had the browser freeze with my 2080ti but it would occure a couple of times a month, it become more common since installing the 3080 which I will say has been superb for games, not a single crash in cyberpunk and I been playing in 5-6h stints (nearly 50h in total) - this is after C9 firmware updates and latest drivers.
I do feel it's related to a bug in windows and it's impacting Nvidia drivers negatively.
Just a side note, when I had the browser freezes with the 2080ti the screen would be garbled before the reboot. After plenty of testing it turned out to be memory. Since I moved to 2 sticks of Patriot 3200 the freeze wouldn't be garbled. O originally had 4 sticks of Corsair Vengeance Pro RGB which proved unstable.
