As said in the title, while playing star wars the old republic, my laptop just shuts off. wasn't sure what it was until i touched the bottom of my laptop and it about burned m fingers. I am prettttty sure the over heating is causing it to cut off, as I see no other reason. Any suggestiongs for quick/free or cheap fixes to this issue? PS as I am a noob I don't want to take my Mac Book apart and remove the thermal goop.
