Weird Game Noises from my Laptop?

-it sounds like a game. i want to say it sounds like a spaceship.

there's nothing unusual happening with my computer, its been pretty normal. but it just started happening today, like four times. it really creeps me out. i feel like i've been hacked or something, but i've heard that if your computers being hacked you'd have a lot of pop-ups, which i don't have.

please help :(

anything is appreciated(:download Spybot Search & Destroy from : http://download.cnet.com/Spybot-Search-D鈥?/a>



update it and do a full scan if there are any spyware trojans or such like then this will find it and with a few clicks your pc will be as good as new again.
