Weird problem on powering on.

I've had a lot of bad luck on my new build. Asus Z97-A 3.1 mobo, EVGA GTX980, Corsair 16GB Vengenance, Corsair AX860 PSU, 2 SSD's a 1 HDD. 4690k. Not doing any oc'ing as of yet, cos well since day one, i've been troubleshooting a problem one way or the other.

First problem i had were no drives being recognised. Thought i had a bad mobo at first. Done an RMA on that, rec'd the replacement next day and replacement was doing the same thing. Yep all four of my drives were dead. Confirmed by taking apart the drives and checking the pcb boards all burned. So that PSU is on its way back to Corsair for an RMA.

Took a good known to be working Corsair AX760, that i had previously working, without issue, and replaced all my drives, (2 new SSD's and a new 6TB HDD) rebuilt to Win 10 64bit, spent a couple of days re-downloading all my steam games, and restoring all my backups, and everything is working great !!!!! EXCEPT that maybe one of four starts, the machine gets to where the windows logo appears, then the entire machine just shuts down forcibly.

WTF ? So thought, how unlikely could it be that my PSU has started having problems? But hey, no more unlikely that all four drives dying in one clean sweep. So lets not count anything out now.. Cos it does sound like a bad psu, right?

Swapped out the PSU again, with another known to be working AX760 (i have three gaming rigs in my household, 1 for me and 2 or my kids)

And its still doing it........

I don't want to RMA the mobo again, as well i RMA'd the last one, and there was nothing wrong with it.. It was the PSU that caused the problem.

But what else could it be? What could cause a machine to shutdown soon as it see's the windows logo ? once every few starts.

I'm going to need to dig deep here, if anyone has any tools to recommend that will test my hardware inside & out, then throw that tip my way, cos it could very well be another bad mobo, i'd of said a bad psu, but i've pretty much ruled that one out. Could be when the sound part of the mobo gets initialized it shuts down... That must require some drawer in power. perhaps something is flaky there in a capacitor on the mobo. but its only affecting it every now and then.

Been doing this for a long time, but occasionally these tail chasers can get you. So always good to tap into other peoples thoughts.

I should also add, i had the GTX980 running on my old P8Z77 mobo and i7 2600k rig, and it wasn't having any issues, so i think i've ruled that out also.. (could have been when it goes to initialize it, something goes wrong)

I feel your pain - been there before.

The only thing I can think to suggest is to build it all with the bare minimum attached outside the case and see if the problem can be replicated.
 
Hi, the moment when the windows logo shows up is the moment when the drivers get loaded so basically it could be everything that do have a driver. Did you already try to boot into save mode, delete all driver (best with a third party tool like driver fusion or similar) and download and install them again.
For a basic test of CPU/mobo/RAM I like to use prime95. It is not that deep but it can find a lot of issues and you can test all at the same time to also see communication issues. To test the graka you can use EVGAs OCscaner but if the card did run in another system it should be fine.. Have you checked in the BIOS if the RAM is set up correctly? Timin/Speed/Voltage. If the RAM is not running correctly it could also cause issues like this. Are you able to test this also in a second system?
 
I went into the event log and noticed bonjour was causing a boat load of errors, so disabled that, and i also turned off fast boot/start. and so far for the last 10 or so starts its been ok... Had to leave for work, so left it at that.. But if its the fast boot, then i can live without it.. Perhaps there's some driver incompatibility somewhere that doesn't like the fast boot? who knows... if it does it again with it disabled, i'll be annoyed. 10 boots isn't enough to slap it with the resolved sticker !
 
i think dom suggests some great things to try
a driver or a voltage set wrong would be my guess too

and if you havent alrdy id just do a clean install or a 'refresh'
