Yup, Dust Puppies can be a problem. More recent computers have a temperature sensor that should go off should you go above the recommended temperatures. See if any fans are not turning, especially the one on the processor. If that's so, then get thee hence to a technician (the removal, thermal grease, pin orientation, etc., is not something for the uninitiated..;).
