Graphics Getting Stuck

While working or watching videos online the Macbook pro freezes for some time.

This has been happening with a wide range of apps.

I mainly use the graphic designing apps for my work. The first thing that i notice is that the Macbook Pro starts heating up and the fan turns on noisily and then it freezes. This starts maybe after 15 minutes of using the application. Sometimes i have to force quit the application or sometimes I have to force restart the Macbook.
