Two thing - right-click on cd icon in My Computer and then click on Close Tray - or - look at the front of the cd drive and you will see a small hole, get something like a straightened out paper clip and gently push the end into the hole, this should open your tray .. and don't worry, that is what the hole is there for.
thanks guys....still trying the pin hole method, but noticed something with the drives
2 trays on pc, DVD-ROM and CD-WRITER and its the first one thats stuck. When i open My Computer there is CD-RW (F) which sure enough has EJECT command, works fine. But nothing about the DVD-ROM drive. Has this gone awol
