Mouse + keyboard not working in games

[Flacker]

I've always tried looking on here for answers on computer questions and such, I finally made an account. I looked around on the forum, but I haven't seen any posts with my particular issue.
My keyboard and mouse won't work in games and my keyboard stops working in YouTube fullscreen mode. Power is still going to them (LED's work) but they don't respond to key presses and such. They work completely fine on desktop and surfing the web.
Key board is a Logitech k120, mouse is a Logitech g502 Proteus Core. I can post computer specs as well if any other info is needed to fix this issue.

Thanks for the reply monicadawson. It means alot. After some diagnosing of my own it came up that my g933 headset was causing the issue. Sadly yet again I've had an issue with Logitech products (I feel inclined to call them "illogitech", haha), I got a replacement headset. Being able to deactivate sticky keys would be help to me, I game quite a bit and there has been instances where sticky keys became a problem, I also don't have the steadiest hands in the world so messing with those settings will help me. Thank you, marked as an answer because you solved another couple of my issues.
