I was using an electric perforater to put holes in paper . The lights would dim when I touched the perforater to the paper and I could hear a sound corresponding to the cycles per second of the perforater coming through the speakers even though the perforater was not connected at all to the computer. Now I can't get any sound from the computer. When I check on the computer to see the sound level and mute everything looks OK. The vertical meters are even moving so there apparently is sound occuring in the computer but it is not coming out the speaker output. Ther are no headphones connected and I checked the speaker connection. Could the high voltage of the perforater have damaged something? If so is there a way to find out waht is damaged without taking it to an expensive repairman? Thank you

It's most likely the speakers are damaged. Try the speakers in another computer or connect them to an mp3 player, etc. to test if they work. Also try another set of speakers or headphones in your computer, to ensure the soundcard is still working properly. .: Fast-Eddie :.
