Every time I right my Minecraft it stops responding?

Hi! So i'm a Minecraft nerd yadayadaya
So I played today and fullscreened. As I started punching, my minecraft would randomly close itself, by that I mean it would minimize into my taskbar. It's hard to re-open and when I play Minecraft on a smaller tab, I can see it say "Minecraft not responding". This started today please help me. EASY 10 POINTS!

Try other games on full screen, if they minimize then that means something you recently installed is causing this problem, if so then delete it, and check in you task manager in the processes bar if anything unusual is running if so kill that task.
