In most cases stream interruptions are caused by one of two things
- Dialup connectivity to your Internet service provider with speeds that are less than 32kbps. If this is the case you must have at least 32kbps to listen uninterrupted.
- Default Buffer settings in Windows Media Player are two low. Go to the Preferences of the Windows Media Player and increase buffer by 4 times the default setting.
Your computer is very powerfull and the internet connection is fast. Try to increase buffer size in WMP.
