Pixel-y squares show up on screen (due to graphics card or software problem)

G'day hows it going, I have got a GTX 560 that I was given from my uncle to put in my new computer build.

The card works fine but when I am sometimes watching a movie, or playing a game, pixel-y green squares come up, but the thing is, I can put my mouse over them and take a screenshot of them so my guess is that it is a software or driver problem.

I have re installed Windows (Windows 8.1 Pro 64bit) and re installed the graphics card drivers multiple times.

If someone knows a work around or a resolution to this, it would be much appreciated. Thanks.
