Windows 7 Pro Sound / Popcorn Popping or Arcs

I have a Windows 7 Pro system that suddenly developed an annoying sound problem.
It's using a Creative SoundBlaster Audigy 2 (WDM) PCI card which has been working fine for years.

Now, after listening to longer tracks of music or ... or just any old time ... the speakers start outputting loud snapping noises like popcorn popping.  They sound a bit like arcs.  

It's not the speakers unless two sets of speakers are putting out power line noises of this sort - which seems very unlikely.
Turning off any of the sources in software has no effect.
Uninstalling the sound card from the Device Manager seems to fix it - so it seems unlikely that the sound card itself is autonomously putting out these noises.

I have tried all of the things I could browse for on the web and nothing seems to help.
Theories include:
- bad PC power supply.
- bad sound card (nonetheless)
- Windows software somehow / reinstall Windows seems a bit drastic....

The noises don't happen all the time and seem to be variable in frequency and loudness.  

There appear to be lots of people who have experienced this but no definitive cause is mentioned.  "try this and try that" seems to be the best advice there's been and seems to have little success.

So, I'm wondering if anyone has any experience and solid recommendations about this.
