Forget about the heating with respect to the one who recommeneded it. The problem that you are facing is that you are using to much RAM It is true that it was working BEFORE what i want you to check is the loads of programes that you have recently installed on your computer that maight be running and using the RAM .... so what I recommend is to delete thoes extra programmes that you have then try again if this didn't work just format the computer and start using it again
