I been having some lock ups, I have a dvd-rom/dvd-rw/cd-rw/ When I try to load Nero my sys locks up, also when I try to play a movie with my dvd-rom using power dvd my sys locks up.

Do you think my sys gets confused, when it looks for the device to play the movie or in Nero case, look for the RW device drive.
