Hi Daz, click on my computer, right click on blank space,click on properties then click on hardware, find the cd-dvd drives and click on the cross, this will show you the cd-dvd drives installed, uninstall all the drives by right clicking each drive in turn and clicking on uninstall, reboot pc then windows should reinstall them, this will take a few minutes if you have several drives,regards Garry
