Self Hibernating Notebook.

I have a Pavilion DV6 notebook that hibernates on it's own while am working. On rebooting it gives me a pre-boosting message of, "System Bios detected that your notebook was put into hibernate to prevent damage from overheating." This just started recently and not I newly brought the laptop. The funny thing is that it happens when am not even doing a processor intensive work(just typing or working on an AutoCad drawing), like rendering( which I do often on it as an Architect) Any pointers to what is wrong or how it can be corrected?

Thanks will have a look at it too.
