I recently bought a Philips CD/DVD Burner8931 and I am having trouble with trying to burn a CD. I try to burn it but it says that there is not a blank cd. This is an internal burner. My computer is a Dell Dimension in the 600's and has Microsoft XP Running on it. Also, it is not reading any disks I have put in it. I have not yet tried a DVD. Do I need to install software or a driver. I did not get one with my purchase.
