Defrag process causing audio interference

[turbines]

I have developed a puzzling problem. When ever my hard drives are being defraged I can hear static in my TV Tuner card audio output. I also hear static when I move the mouse or the mouse wheel to scroll. This problem occurs with Diskeeper 2007 and O&O Defrag V10 Pro. The problems go away when these programs are uninstalled. I have run my Hauppauge GoTV tuner card for a long time along with Diskeeper V7, 8, 9, 10 and 2007 and never before had problems with on this system. Any help on this would be greatly appreciated...

I just noticed that I can also hear each key as I type this....a subtile little tic as I hit each key. All of this goes away when the TV tuner application is shut down.

That can be a very difficult thing to figure out. Any changes to the locations of any electronic devices near the computer? Any new devices attached? Or any changes to the wiring configuration in the back?

Try moving wires and devices to see if the trouble is at all affected or attenuated.

Yes thanks I have already tried repositioning wires, checked IRQ and also swapped PCI slots. I have also tried two other tuner cards with the same results. I do have a wireless phone installed nearby and will try unplugging that.
