I am going through a very serious problem, my laptop automatically shutdown every after 30-40 min. I thought it was a software problem, I was using window 10 single language, so I change my OS to Windows 7 ultimate service pack 1. But even after this my problem does not solve. I use my laptop for learning SolidWorks and for other daily stuff. Is it because I was using SolidWorks on 4 gb ram. When I contact dell support they told me that it might because of two reason either software or hardware. I know there is nothing wrong with software, so what could be the possible reason for shutting down my laptop. Please note this problem of auto shutdown persist even when I use my laptop just for reading pdf book or during surfing. Here I have attached the system temperature.
