I have recently noticed a buzzing noise coming from the top left hand side on my laptop. The noise is a ticking noise which becomes louder when i open up several browsers. It occurs as soon as the laptop is switched on and is very annoying. Another thing is that if i press where the noise is coming from the noise gets louder. Any help would be appreciated.

It's the HDD fan
Open case & clean it,
use wd40 but be careful not to get it on other components
