I have a dell inspiron 1000 laptop and the CD drive, while I was working(i am a foreign exchange analyst and i type and use a program from the company i work for) on the laptop, decided to stop responding to the computer and would not open. I do not know why this has happened but ive shut the computer off and on and then tried opening it and it didn't work, and i'm not sure what to do. any help would be very much appreciated.
