Graphical Glitch

I am getting this glitch in any version of minecraft I play. (Image in folder)
I have said that it is 1.7.9 but it affects all versions of minecraft.
I has only recently appeared, and I am unsure what is causing it, any form of minecraft modded or vanilla are affected by this glitch. I presume it is my pc but I am unsure what would affect the game in such a way.
