Computer suddenly just shut off, won't turn back on

[GaryTheSnail]

I was playing The Divison and my computer just shut off and won't turn back on. When I press the on button everything comes on for a slight second and then turns off and nothing happens when I press the button again. I'm seriously crying right now hoping it just overheated and nothing else happen.

Hi, please take a look at the steps mentioned here: http://www.computerforum.com/threads/tech-guide-diagnosing-a-pc-which-will-not-post-or-start.209946/

Sounds like a short somewhere. Try a different power supply. Build motherboard outside of the case on a piece of cardboard. Try resetting cmos.

It couldn't be something in the PSU blow?

Could be the PSU is on the way out but more likely a short. I'd recommend taking the board out with the CPU and RAM installed and try running it outside of the case, as outlined in Step 9 of my guide linked above.
