Reflections error please help!!!

Hi I need help with a problem with Reflections that i’ve come through and I cant solve it.

alt text

As seen in the photo the material is “damaged” and on any object that I apply it(The cube).
I checked everything and what I found is, if I turn off reflections(In the inspector) the rare color disapears.If I increase the metallic or smoothness bar it increases and vice versa

Please Im working on a game and this came through and now I cant fix it.

if any info is needed to solve the problem let me know.

(the only thing I know is that, going in the graphics menu if I toggle some of the stuff the problems gets solved temporaly.)

Thanks to the QA Team and especially Marius,
I was told that the problem is caused because of the GPU.
If your having this trouble, that means that your GPU does not suport DirectX11

How to solve this problem?

Try launching Unity using : -force-d3d9
(You may also use OpenGL)
Link for more info/Command lines: Unity - Manual: Command line arguments

1-Go to your UNITY shortcut and right click in it
2-Hit Properties
3-In Destination after the: "C:\Program Files\Unity\Editor\Unity.exe"
You must put the code mentiond before. 
Like this: "C:\Program Files\Unity\Editor\Unity.exe" -force-d3d9
