Since its a laptop, its not easy but tyere is sth u might do to fix that. Its underclocking. U decrease the frequency of the processors core and it will throw away less heat. The risks are that if u try messin up with that without any knowledge or experience u mght damage seriously ur computer.
The other solution u have is to buy a new pc. Since its a laptop,those operations are harder and involve
Higher risks. Theres not much more u can do...
