Asus Z170 pro gaming wont post!

[PNIS]

Hi!

 

My problem goes back some time, ive had problems posting my pc for 1,5 year now, but usually it has posted and booted on the second or third try, and worked completely fine when running, no issues at all when power-on and running, only issue when posting/booting. But today I restarted the PC a couple of times because I had problems getting into bios, its booted on the the third try as usually, but after restarting again after that it won't post. The fans run, peripherals get power, screen turns on, but no signal. Ive read that it can have something to do with XMP settings (witch was why I wanted to enter BIOS), but atm I can't even get into bios, as its not even posting. The booting device led is on, I've checked the SSD, it works fine, and if the SSD was the issue, it would not explain why it won't even post.

 

Ive found similar issues on forums, but they have been resolved by moving ram to different slots or clearing CMOS, neither works for me.

 

I have tried:

-Reassembled the whole build outside the case

-Checked all cables

-Removing all unnecessary cables/peripherals

-used different monitors

-GPU works in other PCs

-Reset CMOS several times

-Removed CMOS battery several times

-Using ram sticks in different slots

 

Any help is greatly appreciated:)

I can't find any MEM-OK button, possibly its not on ITX-boards.

Update: it posted and booted now on first try using HDMI-output on mobo, ive tried several times with DisplayPort on mobo without success, ive also tried hdmi and DisplayPort on gpu without success.

 

It seems then the issue is not posting/booting, but getting a signal to the monitor. Might it be my PSU struggling to power GPU? I also tried an old gtx 770, but this didn't do much.
