Cillian, if adjusting the angle of the screen fixes the issues with lines going through the LCD, you could have issues with the display cable. The freezing of the screen could be a memory issue as well as a GPU issue. Try an external monitor and see what you get.

If that works, you will have to take your laptop apart and take a look at the cable and connector. I would also recommend to change the thermal paste on the GPU/CPU etc.
