MSN, The Microsoft Network, may be unable to detect your sound card, or

If a sound card is installed in your computer, verify that a Windows 95
sound card driver is installed. To do so, use the following steps:

1. Click Start, point to Settings, and then click Control Panel.

2. Double-click System.

3. On the Device Manager tab, double-click Sound, Video And Game
   Controllers.

If a sound card driver is listed, you need to determine if the driver
is configured correctly. Contact the manufacturer of the sound card for
further assistance.

If a sound card driver is not listed, use the Add New Hardware tool in
Control Panel to install the sound card driver.

For more information about how to use the Add New Hardware tool, please
see your Windows printed documentation or online Help.
