Pc turns off randomly

[Vastery]

It started yesterday, I cleaned up my pc and swiched from dvi (dvi to vga connector) to hdmi. Everything was fine, whole day passed and the next day it just shuts down randomly. Its not overheating, its not ram memory, all cables are plugged in, I dont know whats going on.

When it shuts off, is it just "poof" it shut up, like someone unplugged it, or is it actually going through some sort of process then shutting down, or freezing and shutting down?  

 

If it's just completely shutting off, you may have a power issue.  Either PSU related, or power strip if you're using one.  

 

Other than that, my initial thought is almost always RAM.  I'd clear the CMOS on your Motherboard and start there.
