So over the last 2 weeks my laptop screen has been doing some weird stuff. Out of nowhere it will freeze, turn black, show some glitches (it'll kind of look like the picture below) for about 1 second, go back to normal, and then freeze and turn black 1 or 2 more times. When it's done doing whatever it's doing the screen brightness is suddenly set to the max and it doesn't change, even though the screen brightness bar in the settings shows that it is supposed to be changing. I've found this problem usually happens when I'm in a game and running or compiling code (I'm a hs student so the code is nothing crazy). The black screen kind of reminds me of what happens when I install the graphics driver. Unsurprisingly, reinstalling the graphics driver fixes the issue, but this doesn't prevent the problem from returning. I'm using a GL702VM and I have undervolted the graphics card and cpu, but it was undervolted before these problems started appearing. Any tips?
