Asus Z170 pro gaming doesn't turn on

[Bjorn Samuel]

Yesterday I was building a gaming pc for a friend of mine and I needed to update BIOS for the mobo to support 7th gen intel cpus. For some reason I ended up to running the ez tuning thing and then things started going south. Screen went black, I waited for ~10 minutes and tried to short the power pins to shut down the pc. It didn't work so I ended up turning my psu off and after that I can't get the pc to boot anymore. Even the psu fan doesn't spin. All the qled indicators are off which means, I believe, that everything should be fine. System power led is on and so are the other leds on the motherboard.

Currently these components are hooked up:
Asus z170 pro gaming
intel i5 6600k
1 stick of Crucial Ballistix Tactical 4Gb 2666mhz
Seasonic 620W M12II-620 Evolution
Note: cpu, ram and psu are my own and do work with my own z170 pro gaming motherboard

Here's what I have tried to solve the issue:
-All different ram configurations
-Resetting CMOS and switching the CMOS battery
-Used different ram and psu
-Switching CPU OV on and off (not sure if it does anything but anyways)

Needless to say I've had no luck so far. Please do suggest if you have some tricks up your sleeves. Otherwise I'll probably end up RMA'ing the product and paying testing fees and eventually buying a new motherboard. (And yes, my friend has my mobo now and I'd hate if he would have to pay for a new motherboard if I screwed up. I'm a true friend you know ) All help is appreciated, thanks!

The board supports "CrashFree BIOS", so you might want to try that.

Cutting the power while updating the BIOS (even if you waited 10 mins) is never a good idea.

Looks like you can create a USB, or can use the disk that came with the motherboard to recover.

Thanks for your answer, I'll check it out. But am I able to do this because I'm not able to boot at all? Also what can I do if I come across this type of situation again where the BIOS update or something results in black screen and the pc is still running?

Edit: "Step 1: turn on your system." I guess I can't do this.. I'm wondering what can cause a motherboard to not boot at all. Though I've read that people have had problems with this motherboard suddenly dying after x amount of use etc.

Do you have any signs of life in the system? If so, that would likely be sufficient to be deemed "turned on".

It doesn't require you to do anything beyond turning it on & inserting the disk.

The problem is it' hasn't turned on since the ez tuning episode.
