Question about Boston Acoustics BA745 Computer Speakers
The contacts on the volume control (potentiometer) get oxidized over time on any analog rotary volume control. With the power off, crank the volume control back and forth real fast for a minute or two, this will do the most cleaning of the contacts that you can do without access to the insides. Ultimately you'll probably need to sprary some tuner wash/tuner cleaner or other electronic parts cleaner in the know (with the electricity disconnected) and then work the knob back and forth. Tuner wash bottles are available at electronic specialty stores or radio shack and usually have a long extension tube (like what comes with WD40). You might be surprised where you can reach with the extension tube.

try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the sound card and the CPU central processing unit dust causes static to build up in a computer causing it to overheat any many other problems
