it's probably overheating... have you ever cleaned it?
You can take it apart, the fats get obsurd amount of dust that screws airflow... reapply the thermal grease.
But it takes a long time, if you're not careful you can screw it up. And if overheating isn't the problem or it's too far gone, this isn't going to fix anything and it might be harder to resell to gamestop etc because you broke the seal (if you already haven't).
The safe thing is to trade it in, and if for some reason they don't let you resell (I don't think this will happen). Then clean, etc.
