I just got a new pc in the past couple of days and Ive just noticed that when I open a program my pc makes strange high pitch noise(not very loud). When I close the program and return to my desktop the sound stops.
The fact I cant tell whats making the noise is driving me nuts lol. Ive had the case open to have a listen, but all i can tell is its maybe coming from the processor or around that area.
Does anybody have any idea as to what could be making the sound?
