Problems with your PC’s DVD Drive not reading your disc
If you insert a DVD disc into your computers DVD drive and the light showing the disc is being read stubbornly stays on, that is probably as far as you will get, and the disc itself will not be read or actioned.
The simplest explanation for a problem like this is that your DVD disc just needs cleaning. Also make sure that the disc is not scratched or damaged in any way.
If the problem continues try cleaning your DVD-ROM Drive. Its best to blow out any dust using a compressed air can. Alternatively, use a CD cleaning kit, which should work just as well.
If the problem still persists you may need to replace your DVD-ROM Drive.
