Question Black screen following windows update. Need confirmation

[sideswipev2]

Hey folks.

Left a Windows update 2 days ago and when I came back the PC had restarted but was just on a solid black screen. I restarted the PC as I couldn't get the screen to wake up, etc but got the same again - no BIOS, no cursor, nothing.

Ive tried following various bits of advice through Google searches but no success.

So far I've tried:

• various combination of keyboard presses to wake the screen
• checked all cables were connected properly
• used different single monitors rather than the usual 2
• unplugged all USB devices and restarted with just a monitor plugged in
• switched the ram about/used 1 stick at a time
• removed the graphics card and tried with 1 monitor into the motherboard
• turning it on with no ram and no graphics card (restarted itself every couple of minutes on this one)
• reset the bios on the Mboard using jumpers - when shifting it to the second position on a 3 pin mount it wouldn't turn on
• reset bios with the battery method

Each time it turns on it sounds like it's running fine, and the monitor isn't showing a 'no signal'. It's just a black screen. I thought maybe the update had corrupted windows or something but then i can't boot from a USB to repair if I can't get anything on the screen. So now I'm assuming it's just coincidental timing and the motherboard is done. PC has been running fine for a long time now so i wanted to be thoroughly sure of my options before committing to buying a new board.

Specs

-Asrock z97m pro4 motherboard

• i7 4790 processor
• gtx 1080
• corsair cx600m power supply
• corsair vengeance 16Gb ram

If anybody could give me advice or confirm my suspicions that would be great!

take gtx 1080 out, and test with the igpu

I've tried it with the 1080 out and the monitor plugged into the hdmi slot on the motherboard but it was a no go as well!
