Try restarting the system into Safe Mode and then do a clean shutdown. When Windows restarts, it may fix whatever problem you are having. Have you been trying to update any drivers? A botched driver install will also do the same thing as you are experiencing.
If the first thing I recommended doesn't work. The second thing to try is to uninstall the optical drive in your device manager, restart, reconnect the device, and let Windows re-install the drivers for it.
