I was GIVEN an 8/9 yr old PC which had several problems once I got it HOME and plugged in so I had to have a NEW hard-drive fitted.

Got it home again and could not install the internet disk due to numerous errors so took it back in and it all now works (fingers crossed) EXCEPT for the sound/speakers.

If I insert a CD windows media player plays the disk but there is no sound. The same happens with the DVD player (powerDVD). I think there is also a problem downloading/playing clips/music from the internet.

I rang the shop and was informed that the speakers should be plugged into the GREEN holes on the back of the tower. I have checked that this is where they are plugged in, and they are.

Can anybody enlighten me as to what the problem now could be and how to fix it please?Look in control panel and see what sound devices are listed in System/Device Manager. Any yellow exclamation marks?

Is the speaker icon in the system tray (lower right of the screen)? Can you click on it to adjust the volume and make sure it is not muted?

Try other speakers on this machine and try these speakers on another machine to pinpoint where the problem is, if all the above checks out OK. Hi GX1_Man - thanks for responding ,

Just checked and no exclamation marks, just normal looking icons, checked if the speakers were muted and all up high but I don't have another set of computer speakers, I was given this PC for internet use and don't even have a printer yet !What sound device is listed? Did you look in the sound portion of control panel? How about the mute checkbox?

Also, make sure you are plugged into the right hole. Pale green is usually it, if present, but you can try the others. It won't hurt anything.checked all those then changed the socket the WIRE was in and the speakers are now working - THANK YOU!!Thanks for posting back!
