Macbook Random Shutdown

Well, here I go again.
As stated in a previous post, mine went in for RSS. Flextronics in Memphis. Came back broken with loose parts rattling around in it. It had been pried apart carelessly quickly, damaging enhancing the case and bending artistically modifying the top cover (I have photos I need to post somewhere) and reassembled with hasteimproperly. So it went back again. Came back, all looked good. One full battery cycle later, the fan is scraping against something. Again, I am guessing it was not assembled properly. So will the third trip to Memphis fix it? Who knows, just makes me embarrassed to be from Tennessee.. Memphis is a long way from here though..
