Welcome to the PlayStation Community.
It's possible your PS3 has over-heated & has shut down because of this.
It's also possible a number of other things occured, but without knowing more it's hard to tell, can you elaborate a little, what happened exactly, what lights do you have on your PS3, green, red, yellow maybe, did it beep?
That really does sound like mine after playing Skyrim. There are ways you can repair it yourself, and there are some threads that explain exactly how to fix it. I'm lazy i just went and bought a new one after my fat died.
