Try removing the CDROM in Device Manager, rebooting, and see if Windows puts the driver back again.
Sorry to say the CD might be dead, but you have to cross check as many ways as you can to be sure. Another check is to watch and listen. Does the light come on at all, and can you hear the disk spinning up at all - as well?
Assuming of course that you haven't been inside the box and disturbed the power and data cables. Even with a non-working laser, the disk will probably give a brief spin before stopping and developing "cloth ears"
Just a little more info. that may be of use. Both my drives refused to autostart on inserting a CD, going into "My Computer" and right clicking on either drive still refused to show any info. or requested me put a CD in.
They had been working fine up to installing a couple of M/S up-dates and a new program. I did a right click on each drive and chose properties, from there I chose, up-date driver. Even though the message came back that windows was using the best driver, once I clicked OK and exited, both drives worked fine and would recognise the auto-play feature from then on. So it's always worth a try before seeking more drastic action.
