Computer sometimes starts up then shuts down, other times it doesn't start up at all

So I built my 2nd computer a few months ago, and everything was working pretty well until yesterday.

Here's the story in full:
I go to the computer and I notice that I must have forgotten to turn it off the night before (it was in sleep mode), so I wake it up and use it for general stuff for a bit (plugged in my phone, put on some music, etc.). After 10 minutes I leave for about half an hour, but when I come back I notice that it had shut off (I did not do this myself). I press the power button and it boots up to an error screen saying that windows didn't load properly... well shit. I shut it down and restart and it turns on normally; I even manage to get it to the desktop, but then it shuts down again. After this, whenever I pressed the power button nothing would happen, no turning on, nothing (except the back fan would slightly twitch). I didn't exactly have time to deal with it so I left and tried again this morning. I got it back up to the desktop, but then it shut down again (should probably mention: none of these shutdowns had an error message, blue screen, etc., it just went from desktop to off). Now nothing happens again when I press the power button.

Not really sure what to make of this.. could it be the power supply? Motherboard? CPU? It seems that all my files are safe as when it does want to boot up everything runs normally for the minute or so that I have, so that's good. Worst comes to worst I've got an NCIX nearby that can take a quick peek, but if possible I would prefer doing it manually.

Almost forgot, if you want them, here are the build specs: http://ca.pcpartpicker.com/p/crmQxr

If there's any more info that I can give to help, please ask!
Thanks! :)
 


Sorry about replying to this so late..

I took a look and couldn't find anything out of the ordinary, everything seemed to be plugged in where it should all the way. Unfortunately, I don't seem to have the time to sort this problem out on my own (hence why I am replying to this so late; not enough time 🙁 ) so I decided to just hand it over to NCIX for a week.

Sorry about that, this thread is a bit of a dud now...
