Hi

I have a Speedlink Medusa ProGamer 5.1 headset with USB connection for power and separate connectors for sound input. It's not a USB headset, just needs the power...

So anyway... once I pop the sucker in (USB), I can hear
- mouse movement
- hard drive access
- graphics card activity
- scrolling documents
- etc.

over the headphone. It's a slight buzzing noise and it's annoying. This is all without any kind of sound input from a soundcard, just from the USB connection.

I didn't have this on my previous PC.
Which USB port I use makes no difference.

Figure this one out! Thanks
