Unknown reason, my cd rom drive door no longer will open. Drive is empty of disc. When button is pressed, the drive door light flashes but won't open. Tried "eject" in properties. No movement. Device Manger recognizes drive. "Device is operating properly" is the troubleshooting report. Computer is less than 3 mos. old. Compaq Presario desktop, running WinXP Pro. Have previously often had problem burning cds and getting message request "insert cd" or "no cd in drive" when there WAS a cd in the drive. Solutions please anybody? Thanks!
