Screen flickering while gaming. Only happens while chatting

[Schroeder_14]

Hi guys. Would love it if someone can help me with this issue, it has been plaguing my PC since I bought it two months a go. As the title says, If I'm playing a game while chatting on Skype or any other chat program my screen will flicker everytime a person speaks. If I am not on chat the games work with no problems at all. The flicker is very noticeable when playing racing games like dirt rally. It doesn't seem to happen when playing games like battlefield 4 or PES.

I have tried reinstalling windows 10 changing graphics card and a long list of other things but nothing has fixed it. I'm totally baffled by this and need it fixed asap.

I have an msi gtx970 graphics card, i5 processor and 12gb of ram.

Does anyone know how to fix this?

Thanks in advance
