Hello-my dvd/cd drive will not read any discs, nor does it show up on My Computer. The Device Manager shows all is working properly. I have uninstalled and reinstalled, but no change. I have also had problems with the drive door opening, but it will eventually come if I push the whole thing inwards-- I'm not sure if this is necessarily connected to the reading problem. I am utterly unversed in computer maintenance, and would greatly appreciate any help from those of you understand all things tech far more than me! Thank you in advance.
