You are having an overheating issue,as far for the chip it definitely cannot be repaired but certainly be replaced which is to be done by a well qualified electronic technician also the chip is not for sale everywhere as its not a chip which is used on tv sets and common electronic items.If you can manage to open the laptop then open it and clean the heat sink and add new thermal paste on processor and if required make use also of a usb laptop cooler pad,here are some tips for overheating on laptops:
Suff954 is correct. Replacing a chip is not small business.
You can try contacting your laptop's manufacturer, as matter of a fact, it is extremely unusual for a laptop to burn a chip after only a year and a half. A laptop should work without any problems for a minimum of 5 years.
I suggest to you that although the warranty is over to insist upon the manufacturer that the chip was faulty to begin with and that they should replace it free.
