Up until a couple of weeks ago, everything was fine. Then games started randomly going to black screen, sometimes after a couple hours of playing, but only every few days. Then the black screen started popping up every time I've played, usually after a mere few minutes, now it goes blackscreen almost immediately. Computer remains on, but video signal is lost to monitor. Have to reboot to get a video signal again.
Problem started with the last upgrade to 18.5.2.
Now every game is unplayable.
I see this is a very common problem, and it seems there should be an easy fix for it, but knowing software companies, I know that's unlikely.
