My daughter purchased an HP Pavillion XG838 w/ a CD-RW drive about three or four years ago. It has Window ME installed. It has been sitting up for about four months because she bought a new one for college. A couple of days ago I tried to install a program on the PC and the CD drive did not respond. When I put the CD in the drive and shut the door a green light came on like it was trying to read the disk but then a red blinking light came on. What can I do to get it to work.
