Is the disc scratched?
Set your boot order in the bios so that the optical drive is the first boot device. Then put a bootable disk in the drive like an operating system disk, or a recovery disk, or something like the Ultimate Boot Disk (which is free to download and use). Shut down the system and start it up again. Lets see if the drive will function properly outside the operating system.
