Keyboard and mouse unresponsive for WIN7 in my macbook pro

I've been using WIN7 to play steam and pc games on my macbook pro.

But about a week ago, my keyboard and mouse just stopped working for my win7.

It's unresponsive.

I posted a video on YT to show what's going on

I don't know much about computers. I'm not a computer expert like many on this site so dumbed down answers would be appreciated 😀
