(Firstly, i apologize for my poor english, but i will do my best.)

This week i began having an issue while using my microphone in online games, more specifically, Dota 2 and Overwatch. Dota(and Steam) crashes when i press my microphone key binding, and Overwatch doesn't allow me to hear or speak to anyone on the voice chat.
I tried veryfing my microphone in the Control Panel. But then it also crashes when i open the Recording tab in the Sound window.

It might be a driver issue, but i am still lost with this one. Can someone help me?
