Make sure it has power (ejects). Check Device Manager in Safe Mode by pressing F8 during boot. Right click My Computer > Manage. Select Device Manager > View > Show Hidden Devices. Now delete all DVD/CD-ROMs and reboot. Windows will say "New Hardware Found" and install. Check BIOS by pressing F key (correct F key is noted during boot) F2? and make sure BIOS see's the Optical Drive.

That button can be set using the utility on your programs list
