Pretty simple, when you know the moves. Thanks for that tip. It didn't work. The unit doesn't see the disc. Maybe it doesn't see drive D. Kinda know what that is.
        I figure something crapped out inside the unit or my o.s. is corupted (many reasons for that 

. My brother is mailing me the disc so I can reinstall. Hah, probably hear from me on that one, if I'm still able to  get back online.
        So, I'm just going to pull the cd rom, since it's blocking the airflow around my new unit, and not much else. Maybe stick an intake vent in there or something. Couldn't hurt. Discs always seem a little warm. Later.
