Sounds like it's packed up then. When you insert a disc, a disc icon should appear on screen next to the mouse cursor. If that's not showing, the deck isn't reading the disc at all. If it doesn't show as being present in 'My Computer', then either it's not connected, or it's duff! You could try to install it again, by going to 'Control Panel' and going through the 'Add Hardware' programme. But it might have just given up - they seem to be worse if not used for some reason! I had one which I didn't use at all from getting the computer, until about two years later. It worked intermittently at first, then settled down, then decided to b*gger off completely! Got a new one fitted and away I went!
