Ringing?

[Z3RO]

I don't know what's up with my computer, but every now and then I hear a ringing sound through my speakers. It's very clearly a ringing sound, as if my computer was calling someone. I heard it sometime last year. Then it left. And now it's back. I don't know what it is. It comes around every few weeks. Can someone tell me what it is??

Is someone calling you on STEAM? I get that often, people want to voice chat through steam so it make the phone ringing sound..

That or your computer is dialing up..which is ridiculous because who uses dial-up anymore?

Yea,

The first couple of times I heard the "Steam Friends" voice chat ringing I was waaayyyy confused.

Zero get one of your steam friends on chat, ask them to hit the "talk" icon and see if the "ringing" you hear when it starts is the same.

You should then spot the small icon and if you click it you can voice chat to him / her.

I'd have to agree with raven to first check if it really is the steam friends thing, but I'd also check if it wasnt a mobile phone being used near speakrs, either it recieving a text / call it sounds kinda like ringing.
