I recently bought a Pioneer DVD Burner, and it installed correctly... I burned a DVD yeterday with no problems, but when I turned my computer on today the drive wasn't detected by windows... I went into device manager and tried 'updating' the list, but still nothing. 'Add Hardware' also did nothing... I turned the computer off and on and suddenly the drive works! I then turned it off and on again to make sure it was working, and once more it isn't detected... I don't know what's wrong, because sometimes windows will detect the drive and sometimes it won't. There are no loose connections! Any help would be much appreciated!
