No Audio Device, help

[Mellisa12345]

Hi my computer is a compaq and I click something wrong and it turn out to be no audio device in control panel. So I search for some mistake in Device manger and under sound, video and game controllers. Then I found there is a exclamation mark on (Audio device on High Definition Audio Bus). If there is any solution you know Please help me. Thanks!!

You need to tell us the model number of your Compaq computer. Also what version of Windows are you running and which Service Pack level????

If, by chance, you're running XP SP2 the first best thing to do is upgrade to XP SP3
