For some reason my iMac G4 (1.25GHz, 20-inch) makes a buzzing sound (approx.) every 20 minutes and 5 seconds. The noise is coming from its half-sphere base and lasts anywhere from 2 to 5 seconds. It seems to me that the source might be the internal HD, however I'm not 100% sure about that. The fact that the noise occurs in 20-min intervals makes me think that there is some sort of background operation going on.
Has anyone had such experience? If not, then how could I figure out the actual source of the noise.
Thank you.
