My computer shuts off randomly by itself?

It started a couple of days ago and I don't think it's overheating. I think that because I checked under and where the heat escapes and it isn't hot. It showed this blue screen and it wouldn't restart as usual this time too. And, I've unchecked auto restart and it still does it. So what could it be and how can I fix it?
 
in my experience first some simple check .remove ram and clean it and try.
this has solved my problems several times
 
You'd be surprised how fast a system can overheat, I've had laptops in the shop that overheat and shut down before it even reaches the login screen and the air coming out is still cool. Needless to say after a good clean, and some fresh thermal paste, most systems were back up and running like normal.

I do agree with kalarta on the basic checks first before anything else, I would start with reseating the RAM & HD, and then I would run the system from a thumb drive using Ubuntu to make sure It isn't software/malware related.
 
Please download PC Wizard from my sig, install it and run it. Go to FILE, SAVE AS and CLICK OK, copy the text out of that file into this thread. ALso post exact PSU model and brand.
