Listed below are some basic steps to help restore sound to your computer. This troubleshooting guide assumes that your computer has no sound at all. Update Software: Many sound problems are resolved simply by downloading the latest version of the Windows Media Player and/or Internet Explorer directly from Microsoft to use as a baseline test. If you are using Microsoft Media Player, it may be useful to check for any recent updates. To do that, just start the Media Player, click on "Help", then click on "Check for Player Updates..", and it will automatically download any updates. Or, you can download the latest Microsoft Windows Media Player for both PCs and Mac for free from: http://www.microsoft.com/windows/windowsmedia/9series/player.aspx Also, since old versions of web browsers may have limitations or problems, check for any web browser updates, and upgrade to the latest version of your web browser. For Microsoft products, the current status of your software can be verified by the Windows Update web site at: http://windowsupdate.microsoft.com Reset the default BIOS settings: You can try resetting the sound default in the BIOS.

If sound is restored when the headphones or one speaker is plugged in, replace the original sound cable with a new sound cable and test for sound.
