computer not starting up after a shut down

[njc192]

So I built a new pc about a month ago and i have had pretty much no problems except when i play Tom Clancy's The Division. Its a new game and it freezes sometimes so i tried to shut down my computer. Im using an nzxt h440 case i dont know if that matters but i lightly touched the shut down button and the computer shut down. When i tried powering back on, nothing happens. This had happened to me once before but I swapped outlets and did some simple trouble shooting and it started back up. This is not working this time. Ive taken it apart, reseated the gpu and the RAM, and also tried jumping it. The jump did not work. Ive looked up alot of the forums... some of the solutions did not work... and some of them are saying you simply need to replace... Ive done the simple trouble shooting again and all that happens is when i turn the psu off then on again the whole rig lights up for a split second then dies. Im not sure what to do guys... please help!

What are your specs?

msi z97 gaming 5
strix gtx970
intel i7 4790k
corsair 850w
windows 10

I've also been continuing to mess with it... and its really weird.. if I reset the motherboard I can power it on but when I set it to boot the ssd and reset it simply powers down and i cant turn it on until i run through another cycle of unplugging, resetting and turning the psu back on

Do this paperclip test on your PSU. Connect it to just some fans and see if it works.

Have you ever made it to the OS again?

well... I cant say I have an answer for anyone else who has this problem.. but I simply kept reseating the gpu and resetting the mobo and finally it simply booted into windows. i was able to shut it down properly and i dont seem to be having any issues

If you were reseating the motherboard fixed it, there may be a short. Did you only install the standoffs that match the motherboard screws and not the extra ones?

 

[njc192]

yes..... i believe i put all 8 or 9 screws that were available to put in... and i was reseating the gpu.. but it certainly felt like a short... it would not power on sometimes

 

[turkey3_scratch]

That's the problem, I doubt your motherboard actually has 8-9 screw holes that go through it, does it? How many physical circular screw holes are on the motherboard? If a standoff is in contact with the bottom of the motherboard, electrons may drift from their normal path AKA a short.

Thank you so much! I will make sure every screw is screwed in

 

[turkey3_scratch]

No no you're misinterpreting. You want to make sure that only the standoffs that align with motherboard holes are in. The ones that don't remove.
