Other Post like beeps, but after boot... Help, I'm freaking out!

I booted my pc after getting home from work and it made a bunch of weird beeps. These weren't bios beeps, it made the usual 1 happy beep then jumped to windows 7 loading screen, the one before the 4 coloured lights appear. then made 3 deeper beeps, sounded abit like mmmmeerk mmmmeerk meeerrk. These are not grinding noises like a dying fan but an electrical noise.

Please help im freaking out, it just did again while typing this.

 

Were they very quiet? If so, it could be your speaker cables picking up microwaves from your mobile.

 

it turned out it was my new andriod phone being a spanner, i was sitting at my laptop f5ing bit tech while hoping my 5850 / mobo wasnt buggered when my laptop made the same noise. well the phone in my leg pocket did anyway.


Sorry boys and girls, for the panic posting but never heard that noise before and it freaked the hell from me

 

well spotted capnpedro + rep for that mate
