I just moved the computer and re-plugged in the speakers- no sound Help???

What is your sound card built in or pci??

if pci you need to check your sound card if it is in place properly...pci souncard are the one that can be remove in your motherboard..built in is the opposite.. it is included in your motherboard..

then remember that the output speaker is color green..

you can also check you device manage to check if there is wrong in your sound card..

go to start. control panel, switch to classic view.
system, "hardware" tab device mange..check there if there are yellow question mark..if there is yellow you have a problem in your hardware...

There are usually at least 3 connectors that are the same size on the back of a typical computer. You've probably just accidently plugged it into the wrong one. One is for line in, one is for a microphone, and one is for the output to the speakers. Try one of the other plugs (if they are color coded, it is usually the one that is light green in color).
