Do you have a boot-able DVD like a windows 7 or vista disc? If you can boot to a DVD outside of the windows OS then there is a problem with windows, if you can't there is a problem with your DVD drive.

I'm assuming the computer is recent enough that the subject drive is a combo CD / DVD burner drive that can read and burn both CDs and DVDs (or a combo CD-rom / DVD-rom drive, or a combo CD burner / DVD-rom drive).

If the subject computer is a laptop or netbook...
Eject the tray for the drive, and when it has no disk on it, wipe the obvious laser lens with a tissue or a soft cloth, then try reading a DVD.

If that doesn't help....

Combo CD / DVD burner drives have at least two lasers and associated circuits. Sometimes one of those malfunctions and then the drive can only read and burn either CDs or DVDs.
