Hi,
Be sure to unplug our other USB devices and remove any media from the optical drive.
On the Start screen type troubleshooting then Hardware and Sound and finally Hardware and Devices. See if Windows and correct the problem.
Go into Device Manager (Windows key + X then M) and find the optical drive. Go to properties and uninstall that driver and reboot.
If the above doesn't work then install the following Windows 8.1 drivers in this order:
Intel Chipset Driver - then reboot
Intel Management Engine Interface driver - then reboot
