I have been trying to troubleshoot this error for quite some time and I followed the advice of most people on here.
Here are the drivers and GPU I have:
Driver Version – 416.94
GPU – GTX 2080
The process I did was do a clean driver install, look above in this thread. Used the above driver version.
Here is where it got interesting, it all worked without issue. I went to a Lan Party for 2 days and played Overwatch for hours. Came hope and set everything up and again no issues.
There was talk above (or maybe in another thread) where having a second monitor hooked up caused the issue. So I connected mine through the USB C connect to DVI, no dongle, straight cable. No issues, yeehaw!
I decided to kick it up a notch as in the past I would play music through youtube or OBS to record my sessions for review. This issue came back!!!
So, in my experience is Overwatch, with a 2080 does not like any resource running with video load on the second screen. I could load forums or surf the internet, no issue. Add video and the issue comes back.
I did not try a second Display Port or HDMI connection.
