My 7 year old computer finally bit the dust so i bought a 3.10 gHz 8 core processor computer with 16 gigs of ram. Since the beginning the onboard audio had computer sounding noises.........i mean like r2d2!! High whistles and clicks, whirling whining noises that change pitch maybe to the fan speeds. So.......blaming the onboard audio i installed a soundblaster audigy card and am expeiencing the same noises. It is unbearable!! My old computer had virtually no background noise. Any suggestions please!! Thanks. -charley
