Hey everyone for some strange reason my Mac gets what looks to be maybe a hot spot in the lower right hand corner every now and again. I notice it usually most of the time happens when I am playing a game on the Mac for a short period of time....Lately it has been happening more and more even when I do not play a game on the Mac. I will be taking it to the  store tomorrow but I just wanted to see if anyone else has had any similar problems and could shed some light on this. Also what do you think  will do about this problem?

Here are some pictures
