Computer turns on, no display

[Ravenloss]

First, i am aware that there is a lot of threads with this very question already, but none of them have a fix that worked. One day i tried to boot my computer and the fans started spinning and all the lights came on, but there was no display.

I have taken out the CMOS, tested three different monitors another graphics card and another PSU as well, same result every time.

CPU: I7 6700
MOBO: asus 170 pro gaming/aura
PSU: corsair cs750m
GPU: 1080 strix
RAM: corsair vengeance LED 32GB
storage: kingston ssd 256gb and seagate hdd 1tb

EDIT:
I have now also tested another cpu and RAM, without any resoults
I think that the only component that i have not swapped is themobo, but it feels unlikely that this is the issue.
Am i wrong?

Hello... 1) your CPU has a "video card" graphic display device inside it... after a CMOS clear your BIOS settings will default to that device... remove your Video card and plug your monitor into your MB connector for another test.

2) You will need to "enable" PCIe graphics in the MB BIOS "peripherals" (save&exit) and plug in the Video card and Power connectors... connect the Video card to the Monitor for your next test.

Your MB BIOS is the "master control" for hardware enabled/disabled and any special settings for it.

Thank you for a fast reply! Sadly however, i get no response using your method, thus, i cannot get into the BIOS as i get no display

Hello... remove your Video card... remove the MB battery and do a CMOS clear ~2 mins... remove clear... replace MB battery, connect monitor cable to MB, set your monitor for the cable type you are using... try another Test BOOT.

Hello... Different cable?
what video output (cable connection) are you using from the Video card to your Monitor?
are you using any adaptors in between?

Hello... is your Monitor "Auto-detect" or do you need to press the setup button on the monitor to set the cable input? have you checked this?
