I agree with Tmesselt - there is something wrong with your computer. It should not be making any noise as you describe. Doubt it would damage your speakers though.
can PC noise damage speakers?
is it possible for noise from the PC soundcard to damage speakers? I'm not talking about its system sound. I'm talking about noises that the PC makes when scrolling/moving a page, opening a new page, etc.; they're not really sounds, but internal noises. for example: if a scroll a page while the speakers are playing the noises distort the the rest of the music badly.
can these interferences/ unwanted noises potentially damage the speakers is some way?
