Hi all, am using Dell Inspiron 15R with 3rd Generation i7 processor with 4GB Ram 1 GB graphics card and 1TB Hard Disk. For the last few days while working on laptop or using it, it would suddenly shut down without any error message or any information. Again, when I start it works fine for some time and again gets off suddenly as power goes off . Also there is no issue of blue screen or error message. I’ve purchased this in last year September. I am so worried about it and don’t know what to do. Please give me suggestions and help me.
