weird bell sound coming from PC

[Avinoam73]

hey guys! i've got a weird problem:
every once in a while, for a short period of time, i hear a ringing bell sound coming from my computer.this happens with or without headphones and the sound is made by two bell rings one after the other, a short pause and another two bell rings. after that it disappears, and either comes back a few minutes after or just go away completely until the next time. (sorry for the unclear problem, but it's hard to explain sounds)
this happens completely randomly so i can't track it, and it goes too fast for me to check what causes it through the windows sound mixer (i have 8.1). it's not in the windows' sound list. my friend had this thing also. the only things we both know is that we both had chrome opend when it happened. after a full virus check, my PC is virus free.

thanks for the read, i hope i was clear enough!

Something like one of these - http://en.wikipedia.org/wiki/Power-on_self-test ? Beeps come from an internal speaker.

Maybe there's something wrong. Any error messages?

Edit -

OR - been playing any games with bells in?

 

[Avinoam73]

no. no for the games with bells and no for the error message. it might be a self check. it happened one time like 5 times in a row but maybe.

Is this a pre-built pc? If so, look in the manual.

 

[Avinoam73]

it's a laptop, and it it doesn't have a manual...

 

[i7Baby]

It will have, Google it.
