What should I do if I have a buzzing noise from my laptop?

Notebook use out there will be a hum of noise how to do? It's 2 weeks since I last started my laptop, and I can say that I don't really use it for nearly half a year. Think of 51 holiday at home boring on the boot, and friends video again, a sound what ghost, but plug in headphones is nothing, and then began to find reasons for Baidu, said anything, sound card reload Ah, radiator cleaning up ah. Then the eggs, then found out of the stereo, very strange not before AH
