Hi guys,
As the title says my computer is instantly turning off on boot. I've started to unplug items and all I have left is the case fans, GPU, CPU and c drive (ssd) still plugged in and the problem is still occurring. Last change I made was to add another HDD but that was about 4 months ago.
Prior to this occurring I was watching TV on my PC and then switched it off before going to bed.
Wanted to get some advice as to what could be causing this before I try to remove the GPU (cpu cooler off job).

Specs.
Superflower 650w 80plus gold
MSI z97 gaming 7 with i5 processor (the k version from that gen)
MSI gtx 970
2x4gb of overclockers RAM
4 case fans and 2 CPU cooler fan
Windows 8.1


Forgot to mention.
After I unplugged the connectors for the case front panel. The computer did boot up. I switched it off using the mobo switch and then the problem came back after trying to boot it again

Also system wasn't running an over clock.

Thanks for the advice. Going to have to wait till I get home (currently at uni) before I can bench it.

In the mean time I may be able to burrow a PSU from my mates computer (before I move back home). Would it be worth testing out a different PSU?
 
Is it possible for awkward angles and too much stress on the sata connections/cables into the mobo, to short circuit the system. I lightly pressed against them to "straighten it out" and now the system has booted. I've restarted it 3 times using the mobo switch and it has booted up all 3 times. Currently I've left in running for about 2 minutes and it seems fine. If you want I can try and post a picture of the connection.
 
Just an update. The PC has been running for the past 13 hours. I'll leave it on for now and when I get home I'll take it apart and rebuild it.
 
@Smiffy
It is an i5 4690k. I have none of the component boxes with me. when i get home I plan to bench it and clean out components with a can of compressed air.

@XysteR
I did reseat one of the sticks but the other is under the CPU cooler.


Left the computer on overnight and when I woke up it was still running. However today I have had 2 bsods. One was a "kmode exception not handled" and the other was "bad pool caller". I think in both instances I was playing games and watching a youtube video when they happened.

I've also had active tabs in chrome crashing on me. In one instance I was playing games and watching a youtube video when the youtube page crashed. In another instance I had been using a GPU renderer (Blender Cycles) with a web page open on the other monitor. Came back an hour later to find the web page had crashed but Blender was working fine. I have about 20+ tabs open and the rest were fine.

Would it be right to assume that these are related to my earlier short circuiting problem and could this be a sign of memory issues?
