My mp3 player is sick, I think its like a Zen Nano plus from Creative?

My mp3 player has been randomly turning off, its not the battery, I know that much. It sometimes presses stop as well. This used to only happen when I dropped it while it was on, now if I jerk it slightly or sometimes no reason at all it'll turn off. I'm not sure of the official name, but it has the brand CREATIVE on it, says its 1GB memory wise, and Zen Nano Plus, like its model or something. I really love this little guy, so if anyone can help plz do. Looking at its insides the place where you put the USB port in looks like it could be damaged, so I'm wondering if that's the problem, plugging it in, and yanking it out to often to get songs. Another thing, its insides have been exposed before, but I'm always careful when it doesn't have its shell on, it came apart one day, and since then I've been holding it together with small rubber bands, only taking them off and going inside to clean the screen that gets dusty. Or maybe it picked something up off my computer, maybe I should stop ripping off of listentoyoutube.
