...but if I continue to use my computer a while later it will go through the sequence again and I will have sound back. This has happened 3 days in a row. I am playing wow on my primary screen and running youtube or discord or psvue on the second monitor after work.

Typical play sessions range from 45 minutes to 2 hours. There does not seem to be a timing to when it happens. Yesterday I had been playing wow and using discord on a tab on chrome. There was a second tab open but it is just the google homepage. It's always open in case I need to look something up.

The day prior to that I had only been on for about 20 to 30 minutes with wow on the primary screen and youtube on the second screen when the sequence happened. I was in a group so I stayed on and about 10 to 15 minutes later the sequence happened again and I regained sound.

I did run a malwarebytes scan (free version) and did a glary utilities scan (free version). The glary scan had temp files and such to clean up as it always does but nothing stood out as when I ran the scan a second time, it said everything was good. The malwarebytes scan came back negative also. I only run it once.

Tonight I had been on for about an hour when the sequence happened. This time there was an error popup on wow after the sequence that said something along the lines of "3d graphics accelerator has failed" and the game closed.

I googled and was led to this thread: http://www.tomshardware.com/answers/id-3636562/screen-black-sound-computer-restarts.html and it seems to have had a very similar issue but not quite the same. I am not computer savvy and have no intentions of messing with registry files.

I started this thread and the dog needed to be walked. When I returned approximately 20 to 25 minutes had elapsed from the sequence, the sound was back. I do not know for certain that the computer went through the sequence again but I assume it did. Any advice?

This pc is just about 2 years old. I think I built it in August of '16.
