I've got an 800 Mhz Pentium III Dell Dimension desktop. After upgrading to XP, my audio pops and stutters. I've done the following things, with no relief: 1. Upgraded the drivers of my SoundBlaster Live! Value sound card. 2. Upgraded my RAM from 256 to 512 MB. 3. Replaced the SoundBlaster card with a Turtle Beach Santa Cruz card. 4. Shut down every background process imaginable. Any help out there?
