I have a HP ZD7000 laptop running Windows XP PRO. I needed to make some DVD's and was suggested to get Nero ULTRA so I did. The DVD's burned fine. (I did this about two weeks ago). The past two nights I tried loading software and heard some "clicking" noices in my DVD / CD-RW Drive (it has a DVD burner). One time I was able to get the software to load and the other it won't. The light goes out on the drive and when I open "My Computer" it shows that there is nothing in the drive. So I ran HP Disgnostics (inclduing advanced) and it showed that there was not any problems. Previous to my installing the Nero, the only thing I ever heard was my drive would get a little loud but was working 100% fine. Is my problem Nero ?
