Download a program called Killcmos from http://www.download3k.com/System-Utilities/Other-Utilities/Download-KILLCMOS.html and it will remove the password. However, disable your antivirus first.

Try to clean the laser within the dvd drive with a soft material. If this doesn`t work, try to hear if the cd or dvd is rotating in the drive. If not, the drive should be repaired b specialists.

You can replace the disc drive and then do it within the computer itself.
The other option is to system restore to it's manufactured date, with probably 90% of the time is impossible due to memory limitations of system restore. The next option would be to uninstall all programs and services, and running a few different brand virus scans, and spyware scans then uninstalling them as well. Defragment your hard drive afterwards, and clean disk, use Ccleaner to repair the registry (recommend keeping this jewel on all PCs). This is as close as you really want to get to a wiped clean pc without formatting and reinstalling; which we can't really do without a disc drive.
You could try burning your CD to a flash drive, and messing with the bios to let the PC boot from the flash drive and formatting / repairing and reinstalling from there, but that would involve using a pc with a disc drive.
