I suppose you mean you can't get the DVDs working? If so, I've have had that problem with my laptop too (Dell). It sometimes doesn't do anything when I insert certain types of DVDs.
Official DVDs like movies etc it does play but some burned DVDs it does not.
My advice: Try the CD or DVD in a different computer / player and see if it works there. Perhaps one from a friend. This helps identifying the problem to see if it is your CD or DVD-player that is causing the problem.
Best of luck,
