Z270i Gaming - Solid red post LED after VGA driver update

[Farinasaur]

So.. I got a brand new PC and watercooled everything with EKWB blocks.

ASUS STRIX Z270i
I7 7700K
2x8GB Corsair Dominator Platinum 2400mhz
Asus STRIX GTX 1080 O8G
EVGA Supernova 750 P2
NZXT Manta case
Samsung 950 PRO NVME M2 SSD 512GB

After installing Windows 10 x64, I did the drivers installation. Windows 10 asked me to restart the PC due to drivers update for my GTX 1080, so I did.

Right after that, the PC doesn't post. A solid red LED is there on the motherboard QLED feature and the only way to make it post is removing the VGA, so the other leds blinks and the PC starts.

With the VGA connected, I'm not able to boot neither using on-board video, the solid QLED red is there to torment me.

Any idea? I've already removed the watercooler from the VGA and installed the stock cooler, don't didn't worked. I can't RMA the video card due to ASUS warranty void sticker on VGA screws.

Did you test your GPU prior to watercooling it? Also which QLED remains lit?

Yes, it worked before out of the rig. Due to the waterblock weight it stopped without any kind of support so I returned to stock cooler due to Manta case doesn't had any kind of enough space for something to rise it.

The QLED is the last one, I think that's VGA led right?

The strange thing about it is that started right after an driver update...

Can you double-check it for me? Take a photo if needed.

Also have you tried testing your system outside the case again just to discard it being a physical installation problem?

For sure, check the picture.

Remove everything is my last option, hard tubing make it difficult to me 😞

I've put the internal speaker as well, but there's no beep...

I see. If removing everything isn't an option, see if you can test the GPU in another system.

I'll need a friend for that. I bought a GT 420 just to make sure it isn't the motherboard, it will arrive on Wednesday.

Is the red led the VGA ones?

I should be able to use on-board video even if VGA is connected, shouldn't?

From what I can make of the photo, it does look like the VGA QLED. If you want to use the iGPU, you should remove the GPU so the motherboard doesn't detect it and default to it.

is there any chance of the PCI-E connector on motherboard being damaged? There's an capacitor right under the connector and it looks bent, does it have any connection to the PCI-E and maybe damaged the mobo?

Trying to figure out anything before trying the RMA since I watercooler the VGA and void the warranty due to the screw sticker...

Are you sure this QLED is the VGA one? My friend Z270i manual says it's the CPU QLED. Sadly, Z270i doesn't specify.

Sadly I'm not able to test the GPU on another system, only if I pay for a technician do it.
