Really this should not hav gone in the Music, Pictures & Video Forum but perhaps a Mod will move it to a more appropriate forum
Lets see if your DVD drive is OK.
Click the Start Button, then in the menu Right Click on Computer, then in the menu click Manage, then in the left hand pane that opens click "Device Manager" the look down for the DVD drive and click the little open arrow head to the left of DVD\CD drives and that should show your DVD drive. Double click on this and if that says it is working properly click on the Driver
tab and then click "Update Driver" and and choose the top option to auto search for update. Then follow the screen if it finds a better driver.
