Is something wrong with my computer?

I was watching/listening to YouTube on chrome while scrolling through Discord and, what i could describe, my screens (dual monitor) blinked. My video on YouTube froze but audio kept playing and discord window became all black. I can close discord and chrome, but when i try to open them, discord still remains black and chrome won't open a window. This happened a few times before but only Discord. Restarting my computer fixes the problem, but I would like to prevent it from happening again.
