Well, assuming they slapped a desktop processor in that, I can see why it would get hot... but hopefully they wounldn't design a product that is unstable.
You're not, by any chance, lying it on the carpet or your couch when you use it, are you? If so, that could be your problem, as thick fabrics insulate and your laptop will heat up like crazy. Also, if this is the culprit, try running it on a flat surface or raised up by the edges with books or such, to allow air to circulate underneath and see if it gets any better.
Another thing, is laptops just get hot. It just happens. This may lead to the second theorey, that it could be a software, or even hardware problem. I would update windows, (if it will stay on long enough) and whatever else you can (especially device drivers).
You're the guy from that hamburger train, right?
