open up the control panel and double click on 'add new hardware', now follow the steps in the wizard and windows will search for the hardware. You may need the 'driver' CD that came with the sound card, (a driver is pretty much software that the operating system uses to interact with the hardware).
If that doesnt work open device manager by right clicking 'My Computer' and selecting 'properties', select the 'hardware' tab and select 'device manager'. select right click on the problematic sound card, (It may have an exclamation mark in a yellow circle icon), click on properties, click on the 'Drivers' tab, click on 'update driver'. Windows will now have a wizard to update the driver, you will either need to download the driver from the sound card manufacturers web site or have the CD which came with the sound card. Now follow the wizard and update the driver.
If all that fails, pull the side panel off your computer and check that the sound card is not loose, push in the card if it is loose. (try checking help at the manufacturers web site).
hope that helps
