Squealing Noise coming from laptop

[alpacino2368]

Hey guys my laptop makes a weird high pitch squealing noise and Im not sure the cause although I have an idea. It doesn't happen all the time but appears randomly. Now I know most people are thinking its the hdd except this laptop has an ssd so it can not be that. It has a cd drive but the sound doesnt appear to be coming from that part of the laptop nor is the cd drive ever in use. Only other moving part I can think of it the fans and maybe its being caused by dust. Any other thoughts/ideas is greatly appreciated!

What is the laptop make and model ? Also, does it happen when you are on a game menu ?

Asus n550jv and not necessarily its kind of random. I normally notice it when browsing the web. Not sure if it makes the same sounds if the cpu is under load as they are hard to hear under the fan noise.
