When the computer was originally re-set up, my buddy plugged the 120 volt power supply for the printer into the back of the speaker. Now if I move the wire around in the back of the computer, I do receive some static, but, no sound. Did the fact that 120 AC volts, versus 12 V DC ruin the speakers, or, did it possibly damage something in the main board? Any suggestions?

Thank you

Move the speakers to another computer that is known to be good and see if they work. If they do then the problem is with the sound card (which might be integrated into the motherboard). If they don't then they are damaged. It's possible that the sound card is damaged too. Try to connect another set of speakers, known to be good, and see what happens.
