...

its sounds like your case's internal speaker. Try disconnecting it and see if that fixes this
 
Why dont you open up the case, do something processor intensive (like a game of Bf2) then while its making the noise.... simply peek inside the case and listen around to find out which component is making the noise?
 
Open the case and momentarily stop the fans one at a time with your finger (touch middle part... not the fan blades). That should narrow it down.

and what if it is the PSU, got a solution?

edit: buying one would really suck, as i still need to buy a decent sound card, and i cant even afford THATright now....so piling on a PSU would give me even more motivation to get a job....

Vid-card fan or PSU would be my guess. You can feel the vid-card for excessive vibration if you dont touch the components but the green PCB board.
