Hello, buddies!

First of all, thanks for your time and help.

So I have this M18 since 2013, when it was the latest model out there, and after 4 years, it started to make some strange noises last week.

This noise comes straight out of my hardware and it's mostly random (although it is more likely to occur when I'm turning it on).

Here is a recording of it: Vocaroo | Voice message 

It is very annoying, strident and, unlike this audio shows, it is less "noisy" (.e.g., you hear the strident noise stronger, and the air sound of the background weaker).

Today, I have noticed that when I tried to turn it on, I heard a sound if something was stuck, but suddenly released (followed by the noise mentioned [but lower])

I'm not 100% sure if this is connected, but I recently started to have some blue screens, with the message irql_not_less_or_equal (but I believe it was an anti-virus problem, not sure).

It is worth highlighting that I barely use this Aliewanre; it has been mostly shut for the last 6 months and, when I do, I don't go hardcore gaming.

Yes, I'm an idiot that uses an Alienware to work and play GBA and PSX games.

Anyway, any ideas? Thanks for your aid!

Ps: I did that support assistant test, and according to it, all of my hardwares are perfect.
