My Memorex 52 X 24 X 52 CD burner won't burn CD's. It will read anything. When I try to write, it doesn't recognize that a CD is inside. What should I do? This computer has now been rebuilt since this burner was installed. However, it had the same problem on the old version. It used to work, I don't know what changed. I need to back-up my hard drive. It's been a while and I'm getting nervous. Thanks guys, Wanna kill these ads? We can help!
