I run an iMac, with the hard drive partitioned so I can run both Mac and Windows XP, but not at the same time. Everything was fine, then I got a new modem, and everything from Windows (whether Internet or not) has reverb on it and it's sounding like it comes from the bottom of a barrel. The Mac side still sounds good. Mac says it's a Windows problem, talk to Microsoft. Microsoft says it's a Mac problem so talk to Mac. And the ISP says it can't be their problem, either. Suggestions?
