put in a proper music cd, wait about 20seconds, and then go into my computer, look on "devices with removeable storage" and click on your cd drive and tell me what happens.

If it still wont open up/nothing happens that way either then id say it was screwed.

You can get a dvd/cd drive for about £15 http://www.ebuyer.com/product/154832 takes longer to open the pc than it does to install it just a matter of unscrewing the old one and taking out 2-3 plugs, screw in the new one and connect the plugs back in, most likely the same way they came off the old one
