Hello, Deos anyone have any clue as to why my sony vaio laptop just shuts down for no expected reason on its own?

How often and is it when you are doing certain tasks? It may be overheating due to dust build up inside. I had this problem before. Can you download CPU-z to check the temperature of your processor?
