HP 740I does not see DISK!

No matter what type of disk I put in the drive be it CD or DVD (dvd a movie that I bought) it does not see disk. When I insert a disk it does not autorun which is set. If I go to MY Computer and click on the drive I get the message “Please insert disk into drive D” Any help would be greatly appreciated.

Thanks

Possible lens problem? If the drive doesn’t work in another computer then I would look into warranty options.
