Hi I have Sony vaio VPCEB11FD laptop with following spec.

Intel i3 M330
4 GB Ram
320 GB HDD

The problem is if I am ruining some heavy program or opening many tabs on my browser I heard loud fan noise after that my laptop power itself off,
I have opened my laptop several times to clean my fan from dust, also clean the air vent with compressed air .

Cpu temp is around 52C

Any help please :(
