I have a similar situation and can not find any help. I have a HP Compaq Presario F700. Something has happened with the DVDRW drive and I can not find a fix. The first problem I have with the DVD drive is that when it is detected it is as a CD Rom drive. A music CD works fine but nothing else. When a DVD disk is placed in the drive it spins and then the screen messes up with a bunch of lines across it and the computer freezes. Any help will be greatly appreciated.
