I am posting my issue too late than it started occurring. I have a sony vaio with intel core i3-370m,4gb ram,500gb hdd and 1gb amd radeon 5000 series gpu. Its more than 3 years old laptop but i used it with great care so it doesnt look like old.

So here is the thing, my laptop started getting hot on in just using browser and outlook(no so called heavy load, cpu usage 25-50). After few days its fan started making sound. I took it to a technician and he changed its fan. I thought it will be fine now(but that's the day from when i started getting real trouble). Now with new fan(of course no sound) it started getting cold shutdown without any error alert or BSE.

I took it again it to him and he again did all the cleaning and repasting properly(i know the way of using thermal paste). And then technician added that if its still shut down then he thinks he should change the gpu chip. Problem was same so I took it to him next day and he changed the chip again. Then using coretemp and fanspeed. I concluded that its only cpu and core temperature which get high more than 80C even If i open a heavy website or two average website on browser simultaneously. I cant do multitasking on it anymore.

So I told them the whole story and then technician changed the processor. Now i can work on it but its just minor improvement maybe just because its one day old( can say it will shutdown if i open 2-3 browser tabs simultaneously). It will still shutdown without any error if i start working averagely. Its just that now I have learnt in last one month how to stop it from shutting down( by running programs slowly and with time gaps).

I believe its a hardware issue not software as shutdown even did happen when i was on bios. Please guys help me I am being mentally unstable as its behaviour affecting my work/profession.
 
Solution
The possibles reasons of overheating are these:

-Fan not workin
-Old thermal paste/ innapropiate application
-Dust blocking the airflow
-A bad cpu (less likely)

If you dont feel confident about opening your lap, take it to another technician.
