Monitor makes very weird sounds all of a sudden?

[AceIccey]

Okay, So this started yesterday which started to spook me. I was just browsing the internet and then I heard a beeping sound come out of my monitor. I didn't know it was my monitor yesterday then eventually it just went away. Then today maybe 10 minutes ago I heard it again. It went in a beeping pattern of "Beep beep beep beep" and it would repeat that for a while then I turned off my monitor and it stopped. I turned it back on and now its gone away.I have zero clue what it could be and its not coming from my computer because I had turned off my monitor and the sound went away. It spooked me out quite a bit if anyone knows what it is please help. Thanks.

Nope thats not it. A way to describe how it sounds is like a bomb basically going "beep beep beep, beep beep beep" then it stops after a while. It really spooked me out because first time I heard it I thought a bomb was legit about to go off.

I think it could maybe be my hard drive but not sure.
