MP3 and MP4 players give you the ability to enjoy both audio and video files that you have transferred from your computer on a small, portable device. These devices may malfunction for a variety of reasons, including a faulty file on the player or the memory on the player being completely filled. One way to troubleshoot an MP3 or MP4 player is to reset the device. The exact method for resetting these media players varies based upon the device that you own.
