Frames suddenly dropped from 200fps to 60 fps

I turned on my computer, played some overwatch and it’s now running at 50-60 frames when I used to run it at 200ish frames. I checked all the video settings and nothing changes this. I played other games to see if my computer was the problem but nope, just overwatch. If anyone has a solution, please help. The only other thing I can think of is to uninstall. If anyone has any other ideas, please let me know. Thank you
