Hi!

In my area if any computer shut down it self, it means two think !

first: the power bloc is failing, it gives less power then required by the hard (mother board, CPU, GPU, ...)

second: your CPU (processor) is hanging with hot, it's time to clean accumulated dust from your mother board and CPU, with all fan's .
