When I boot up my PC I hear a distortion noise that starts at the windows Welcome screen and continues on for about a minute after the desktop is onscreen. This only happens on complete boots, not restarts, and I never hear the distortion again even if my PC is running for hours upon hours.
Even weirder, I can seem to effect that distortion noise with my mouse, altering the sound by moving it around and rolling the mouse wheel. I also hear the distortion on the Welcome screen at a boot when I move my mouse cursor over the User Account icons. Move the cursor over an Icon, loud distortion noise, move it away no noise etc...
I am baffled. I can't understand what in the world could be causing this.
