Was this from a Upgrade to Windows 8 or did you wipe out the old OS and do a full
installation? If this was an upgrade there may have been an incompatible CD/DVD
program being carried over, especially check startup. Or maybe you installed a CD/DVD
which caused the problem. If you suspect it was an Update use Control Panel - Windows
Updates - lower left Installed Updates - Uninstall the suspected update.
Check the Compatibility Center to see if the drive is compatible :

Check with the System Maker's Support, their on-line documentation and driver/firmaware,and ask in their forums (if any) about any known issues.
