computer won't turn on, motherboard doesn't respond to 'start' button being pressed

[sbeacher]

I came home Friday night to my computer off. I normally leave it on and let it hibernate or whatever. When I tried to turn it on the power button did nothing. Opened the case and my Maximus Hero VIII's LEDs are all on but the 'START' button (which is illuminated) does nothing. Other components in my system which have LEDs are lit (my Kraken X61 and my Grid+ V2) but the case fans don't work (and no case LEDs light up) and my GTX 980 lights don't illuminate (though I am not 100% sure if they would light up without the system being on anyhow)

My PSU (Seasonic X750) fans don't spin up at all but this PSU has like a hybrid mode where supposedly the fan only spins up when it needs it. But I would assume it would spin somewhat at start up?

So how do I troubleshoot this? Is this possibly a motherboard issue? I'd assume PSU but I'm confused because obviously some power is happening since the LEDs on stuff all light up.

This build is just over a year old with all new components except the 980 which was a few years older (and I've since removed it anyhow while testing) and had been running trouble free since I built it (nov 2015) I hadn't made any changes to anything lately. I've never had a build fail randomly like this so I'm not sure what to do or which components to suspect. I have an old alienware system that has a PSU in it but it's not modular and is connected to so many random things in that case that it would be quite a pain to get it out to check.

Hi sbeacher

Sorry to hear you were having trouble but it's good to hear you have a working system. I don't use the new cpu installer tool in fact I didn't even know what it was at first.

There's not much you can do except sell the board cheap for parts or recycle it as you suggest, it's hardly worth having Asus repair it for almost the cost of a new motherboard and to purchase a new one would be likely faster than sending it in for repair.

Just to be clear it wasn't the CPU installation tool that messed it up it was the plastic cover (that I guess is similar? I don't know I never even opened the CPU installation tool) that the motherboard comes shipped with.

The only pros of this is I went ahead and upgraded to a z270 board which doesn't have a lot of the bloat that the Maximus VIII had (sata express, ps2 ports) and the new board has dual m.2 slots. But still, if I was going to upgrade anything it would not have been my motherboard and definitely not after only a year.
