My computer isnt new, i got it from a friend. And lately the CD rom drive is not working(wont open or run a cd when it does) and it is gone from the My COmputer menu. Also there is a red light on the front of it, which is usually green. If i turn the computer off and then back on it will work for a second but then stop again. i know how to put in a new CD ROM, if i go buy one and install it do you think that will solve the problem?
