Computer Turns on the Instantly Turns off.

[lskidson]

I recently got a new computer case and when moving all of my components over, I am running into a problem where when I turn my computer on it will instantly turn back off. It does turn on for a second because all the fans spin for a brief moment.

The computer runs fine when I remove the 8 pin adapter from the motherboard but obviously wont boot.

The first time I tried turning it on in the new case it ran fine. The problem only started happening after I plugged some extra LEDs into one of the female 4 pin Molex connectors. Removing the LEDs does not solve the problem
It sounds to me like a short but if it were a short, the computer would not power up with or without the 8 pin adapter.

I tried the motherboard with a different power supply and not luck. When powered it will turn off and on 4 or four times before staying off.

This is a really odd problem that I just cannot seem to figure out. Im guessing a short probably occurred at some point and probably RIPd my motherboard but if anyone else has any possible solutions let me know any help is greatly appreciated.

Edit 1: It is either the board or the CPU as there are no issues with a different board and CPU and RAM.


Edit 2: Things ive tried.
-Removing induvidual RAM sticks
-No beeps from speaker.
-New power supply
-Only connecting mobo and CPU fun
-Different Wall outlets
-Different starter switches

It might be your RAM I had the same problem I took my RAM out waited 2 minutes put it back in. My PC works fine except my computer only recognizes 1 stick. I have to fix that but I hope this works for you.

Did you do anything with the cooler? It might be that the processor gets too hot, had that with my first build...

I appreciate your reply! I have edited the main post to include a list of attempted solutions. This is one of the solutions I have already tried. Thanks anyway!

Hello! I did not touch any cooling stuff. I have a water cooler and can hear the water flow around in the short time the comp stays on for so I think that would be unlikely. Also, it would probably stay on for a little longer if that was the issue.
Thanks!

You installed the "stand offs" in the new case? Of course only the necessary ones.

Stand offs came pre installed with the case I removed the unused ones.

Try to rma both,see which one is the culprit. Maybe even get a new one for both.

Looks like I'll have to. Something tells me its the CPU where it is the 8 pin that is causing the problems but you never know.

Only other thing that i can come up with is rebuilding the whole pc and hope this fixes a shortage somewhere.Make sure all cables are connected where they should be. Otherwise seems RMA the best option.

Motherboard RMA solved the problem. May have been a faulty board, may have been a short. Who knows computers are picky.

Good to hear! Thanks for letting us know.
