Click on start button
Right click on computer, select properties
look at the left window click on device manager
look for sound icon It is a speaker

are there any yellow or read marks next to the speaker?

If so re install sound driver

start...control panel...device manager ...sound open the sub menu then right click to check the properties it will tell you if your on-board sound or sound card is working

If it's the speakers then try another pair, or use the built in speaker that most cases come with to identify which one it is . If it's the sound card then no matter what you try it will not work, or be distored/choppy. I've seen it plenty of times, make sure the speaker is plugged into the green colored jack in the back of the case. Funny how easy of a mistake it is, but a common one at that. Is the sound card built into the motherboard, or are you using an external pci sound card?

Is there a way to identify whether a sound card is working? How can one tell if it is the sound card and/or the computer speakers that are not working?

Thanks.
