Hi, Sorry to hear of the problem with your laptop,
If you are sure that your laptop is overheating then it will shut itself down to prevent further damage being caused.
You can download Everest from here:

This utility can often provide you with details of the exact temperatures at the CPU, Hard Drive, and Main Board for example.
Causes of overheating (apart from those caused by repairs/alterations made using non standard parts) are usually related to:
1 Build up of dust/fluff on the internal components of your machine (heatsinks/CPU and vent inlet/outlet)
2 Operator error, (using machine situated on soft furnishings/carpet etc)
3 Inadequate ventilation/cooling, (blocked/impeded ducts in a high ambient temperature)
4 Failed heatsink/cpu location (breakdown of thermal paste and/or loose connection leading to thermal rise)
5 Failed cooling fans
Close visual examination and listening intently are reasonable guides to detecting an inoperable fan.
Use of an air duster (cylinder of compressed air specifically made for computers) can dislodge and disperse some dust/fluff
Laptops, despite their names are best used on a firm surface (table top for example) with an adequate air gap underneath to facilitate maximum ventilation.
If your machine is under guarantee/waranty/service agreement then it would be wise to consult them before taking the next step as opening a machine usually invalidates the protections provided.
If you are confident at dismantling your laptop and understand and can apply effectively the personal safety requirements and anti static precautions necessary then the use of an air duster to thoroughly clean out the internal surfaces of your machine is recommended. At the same time you will be able to check the connections any detect any failures or scope for thermal rise.
If you are not confident in this it is best to consult a local competent computer technician to do this work and he /she will probably carry out a diagnostic on your machine prior to work commencing as an extra feature and to ensure that the heat is definitely the issue. It is good to save money but not at the expense of personal safety or causing damage to your machine or data.
Good luck and i hope you manage to get your machine all fixed up
Regards
