Have you tried visiting the computer manufacturer, or the motherboard manufacturer's website and downloading, then installing any updated chipset/motherboard and graphics drivers.. If not, please do.

After that, please try the suggestions in the link below.. Maybe you can find the DVD drive by showing "Hidden" devices in Device Manager.. Then uninstall, then reinstall it.
