Last week my computer crashed down. We can't contact the technician who used to fix our computer. Now we found a new one who can reformat our computer but this time, he installed windows 7. Now, our computer is okay again. But the speakers won't work. Our new technician don't know what is the current problem here. Can you help me? :(

Make sure the speakers are hooked up properly and also that the sound card drivers are installed, you can verify this by going into the device manager. The main speaker wire has to be hooked up to the output of the computer sound card.

If the sound card drivers are installed and the speakers are hooked up properly and your still not getting sound, try the speakers on another computer that you know has sound. If the speakers work then its a sound card driver issue on the original computer. If the speakers don't work on another computer then you know the speakers are bad.
