I have found a potential fix at least one that worked for me after hours of trying. This only happens on D2R for me no other game but this fix has worked and ive been playing without any problems so far.
right click on your Nvidia settings on the task bar > Nvidia Control Panel > 3D Settings > Manage 3D Settings > Power Management Mode > Prefer Maximum Performance
As for laptops you can also try this…
Go to Power Management > Change settings for High Performance Plan > PCI Express > Link State Power Management and change it to OFF.
Then use that plan hopefully this helps for you im on Desktop but it should fix any issues cause by low power to the card.
This is for Event ID : 4101 - “display driver nvlddmkm stopped responding and has successfully recovered” you can check what error you are getting on Event Viewer under Windows Logs > System.
Very probably work on laptop on certain video cards… i try on my desktop 660GTX but… nothing, only black screen, then crash and error report to Blizzy.
Do you have more than one monitor? If so disconnect them and try playing with only 1 monitor.
Have had both these options activated / as recommended here - am still ctd’in regularly. No pattern whatsoever: Can be 2 min into game, can be 1h.
Alienware 17 R2, 3440x1440 (external monitor), 1080 Ti (eGPU), latest driver, fresh W10 Pro install
If you go to Event Viewer what Error are you getting when it crashes to desktop?
dwm.exe issue (which is the first entry in the event viewer seconds after the log file for D2R is created):
Faulting application name: dwm.exe, version: 10.0.19041.746
Faulting module name: KERNELBASE.dll, version: 10.0.19041.1202
Obviously it’s the MS process that sits between apps and the GPU. Lots of folks on W10 forums complaining about similar issues - so referring to those pages for now.
Have uninstalled GPU drivers via DDU and reinstalled the latest one. Not sure if that’ll help. Let’s see.

This issue existed already during beta. I remember ctd’ing when the open beta was live, but didn’t bother raising the issue (as I thought someone else would also run into this).
Seems I wasn’t wrong: Game causing GPU crash - Diablo II: Resurrected | Beta / Beta - Bug Report - Diablo 3 Forums (blizzard.com)
So to me that might be my GPU dying. Since many other titles run without any issues on my pc, I more suspect some D2R sub-optimization issue, however.
Ah my issue was with “display driver nvlddmkm stopped responding and has successfully recovered” not Dwm.exe im not too familiar with that sorry mate 
hopefully your card is fine.
Possibly try this if you are using an external display…
" changing the display scaling setting in the Nvidia Control Panel to GPU instead of display fixed the high GPU usage of dwm.exe ."
There is definitely something iffy going on with D2R though i dont have any of these problems with any other game.
Hehe, thx for your wishes. I really doubt it’s my GPU.
That said, your “display driver nvlddmkm stopped …” also appears always in my Event Viewer (WindowsLogs - System - as a Warning for Display). It actually appears the exact same moment (down to the second) as the dwm.exe event (WindowsLogs - Application - as an Application Error). So I guess your and my issue are tied somehow.
I try the same… but nothing change. 
Not sure if you have a stable game by now. Some folks report that a 60 MHz (vs say 100 MHz) monitor refresh rate has made their game stable. Might be worth a shot.
The same thing occur if you have insufficient RAM. Crashed all the time, then increased my RAM from 8GB to 20GB. When running the game 10GB is in use and that has fixed my problem. Crashed only 2 times since which I am pretty sure is due to overheating of my laptop, so better cooling is the next project.
Wow i have been having the same problem.
Display driver nvlddmkm stopped responding and has successfully recovered. Sadly before the last patch it was random. Sometimes I can play for hours sometimes it just crashes.
I have also tried everything but nothing seems to work. One thing worked before the patch which was Debug mode in NVIDIA panel.
Thanks for the tips. After a year of crashing upon startup, I decided to replace my motherboard, cpu, and ram but kept the hard drive. After replacing, I found out it did not resolve the crashing issue. It turns out the RAM was being undervolted by the mother board at 1.2V when the ram is 1.35V. When the ram voltage was bumped up, Diablo 2 runs without any crashing issues (even with Chrome open). I suspect it was also a RAM issue issue in my old system as it would only recognize 2 of the 4 dimms.
