I've been having these problems for a very long time and it is annoying the hell out of me, and I am almost at the end of the line here. It happens when I play games, watch videos online and normally. It is always unpredictable and sometimes it will be good for days on end and it will suddenly occur and catch me off guard. Every single time I have to do a forced reboot and I am starting to worry that doing so will damage my compute more and more. I have tried every thing I googled regarding this issue, right down to uninstalling and reinstalling the driver and it still happens. It happened in Windows 7, but it was fixed with a miraculous driver update back then. But when I upgraded to Windows 10 the problems came back with a vengeance. Because of these problems I am regretting my decision to have gotten an AMD card instead of an Nvidia one. And to make matters worse, there was actually an update several months back that made it worse! What gives?! Seriously, do something about this!
