Need help. Issue with Radeon HD 7970 screen flickering

Hi all. I have had this radeon for a few years and it worked fine in my old build. I just built a new PC 2 weeks ago and it is working well, but i'm having 2 issues with it.

 

The one I'm seeking help for here is that I noticed a consistent screen flickering when ever I play videos full screen. This also applies to video games. It will randomly flicker blue and/or orange for a split second and then be fine. Its more of an annoyance but I wonder if its also causing other in game issues (ahem Overwatch). Lets stick to this for now. Here are two videos i filmed with my phone to show what is going on.

On this one, you can clearly see flickering shortly after i enter or exit full screen mode:

In games the flicker happens randomly, but i can replicate it any time i turn my volume up or down. you can see the volume meter in the upper left when i change it or whenever the meter goes away.

Clearly this shouldnt happen, and never did before and I really hope someone can help me to fix this error. Thanks a bunch in advance for reading this and helping me out if you can.
