If your computer is having a heat problem, I would suggest you take it to a pro to get it cleaned if you don't want to do it yourself. Usually what happens when laptops start to overheat is
this. But if the screen is going Blue with a whole bunch of weird text, that might be the "Blue Sceen of Death". The BSOD looks similar to
this and could be caused by the overheating or a number of other things. Hope that helps.
