noise when using windows on bootcamp

Hello!

I found that when i run visual studio on my bootcamp partition with windows 8.1 installed i got very often a strange noise in the top-left part of the keyboard. It is low level but with high pitch and is really annoying to my ears. In osx i never ear this noise, only when using windows and visual studio. What could be the problem, is my macbook or something else?

spec: macbook pro retina 15'' middle 2014

 

Thank you, i've tried but this didn't resolve in my case. I am also using parallels dekstop to boot my bootcamp partition directly in osx....and even if i turn brightness to max or to min the noise is still there
