When I first got the laptop it worked perfectly and I played games without any problems but a few months ago there were flickering pixels of varying colors (usually depending on the color of the background of the game). They are only on objects that you could interact with in some way (say they sky background and different menus in the game look fine, but an object that you can pick up or your own visible self is pixeled out). Any idea what this might be? And if it's an issue with the graphics card can I replace it?
