First idea as always:
Go to Device Manager, expand CD/DVD Rom Drives, delete them one by one (if Win asks for Reboot, say "No" or "Do that later" or what it was. After removing the last DVD/CD-ROM drive, reboot. This mostly helps.
Keep us updated
EDIT: Sorry, if windows did not even recognize them, you are out of luck probably You may want to try the Hardware Wizard and see whether it finds something.
