Toshiba Satellite S70-a crashes every 25 to 30 minutes, I have tried every virus/malware/adware scan I can think of, I've updated, tried a system restore, used compressed air on the fan, tried running on a/c and battery. The thing shut down without warning regardless of what I'm doing like clockwork every 25 to 30 minutes. It's only a year and a half old and this problem started out of nowhere. I've exhausted my technical knowledge and have little funds to work with. Does anyone heave any suggestions?

It stayed out for almost half an hour and with one Firefox tab open hovered between about 47 and 50 degrees Celsius. It jumped up to 60- low 70's once but the fan kicked it up a notch and cooled it down no problem. The fan sounds fine and the temp was pretty steady for the while 30 minutes.
