Inspiron 17r freezes and display show lines

I have Dell Inspiron 17R N7110 and have strange problem where display all of a sudden gets blurred and shows horzontal white lines and few intermediate RGB lines as well... mostly it turns to black and white. After sometime it automatically comes back to normal. It is very annoying as it comes randomly and goes off on wish.

I also have faced the problem that it slows down to freezing very frequently and it is impossible to work then. Can we get some resolution or diagnostic suggested from Dell?

To rectify these issues, I wanted to format and re-install the OS but don't know how to do that as it is provided in one hidden partition on HD. It had Win 7 pre-installed and I have upgraded to win 8.1 recently.

Can somebody help me to rectify these problems? Please reply.
