Did you ever get anywhere with this issue?
I've had my desktop for over a year, and it does this several times a day, usually crashing the programs I'm using.
It seems to be when the graphic chip switches between low and high graphics. It can happen when a video appears on the screen, or even when I mouseover a gif. Recently, I've been getting very bad crashes when using VST3 music plugins, and losing all my work. This is the reason I found your post - I just lost everything I'd been working on for the last few hours, because I stupidly opened YT to watch a tutorial.
I've tried all the fixes I've read on the Net, but can't stop it - nothing has worked. Many dozens of hours spent trouble-shooting.
I've hated my new computer since day one because of this. Actually I bought two of them (one for another family member), both exactly the same, and they both have this problem.
I will never buy AMD again. Before this I had an ASUS/Intel laptop that almost never crashed during 12 years. This new desktop was supposed to be my pride and joy and last me for a decade.
Instead I feel robbed. I can't describe the hatred I have for this company, and what harm I'd do to the coders who have made me miserable every single day that I switch on my computer, and the fact that they couldn't care less that they're making and selling junk.
