COMPUTER MAKING CLICKING NOISE THROUGH SPEAKERS WINDOWS 7

It is a tower design, just was convenient to put in the empty bottom of the rack, so the components and cables are in pretty close proximity. It's not a long run but the Octacapture is rack mounted in the same cabinet where the computer is located. Thanks for all the responses! I had a bit of a 'Doh!' moment this evening when I realized I have the Octacapture and JBLs hooked up by UNbalanced cables. Is there any way in BIOS to bypass the vid card? I think the MOBO has intel video chipset but not entirely sure about that. I am loathe to swap vid card only to find that is not the culprit but I will if I have too. Avast anti-virus (makes no diff if turned off).

The computer is a 2 year old Dell with i7, 3 hard drives (1 is eSATA - no diff if that is disconneccted), video card is a 1Gb nVidea running two 24' monitors in HD, Windows 7 (aero is on). If the computer is off and I play keyboard (Kurz PC3X)В thru the Octacapture stand alone the sound disappears (duh!) so I know for sure it is coming 'from' the computer.Interestingly, but probably not surprising, the sound will disappear if I use the digital outs on the Octacapture to feed my monitors (JBL 4328's). I know that this is not aВ Sonar issue because it is present when Sonar is shut down and I just have the computer on without even having a stand alone VSTi running. Eventually I upgraded my audio interface from m-audio 410 to a Roland Octacapture (USB) and the problem persists. I put in a dedicated TI card and stillВ had problem. I thought for a long time that it may be related to my firewire interface with a non TI chipset on MOBO.

I have replaced the power supply and the main fan. In particular, I would say that this isВ NOT the sound associated with 'computer whine' and not I don't think itВ seems necessarily related to the video card but I could be wrong. I have found a few similar references in searching 'computer noise',В 'mouse noise', etc., but none of the situations seems quite exactly like mine. The noises seem toВ be related to theВ computer 'thinking', drawing windows, accessing discs and, most noticeably and reproducibly, mouse movement which causes a zipper like sound. I am hearing very low level (but none the less maddening) noises from inside my computer coming through both speakers and headphones.
