No Output on integrated GPU

So is just finished my custom watercooling upgrade, hardline and all.

After that i was playing with the gpus and wanted to flash a new bios.

And so i flashed a new bios on both cards. Initially it didn't work because

of a Certificate error in nvflash, but the i used a version which ignores this

and it bricked my cards. Everything went fine the flashing completed on

both cards.

 

But after a reboot i just get a black screen. So i wanted to use my iGPU but it

doesn't work. I just can't get an image. I even unplugged the GPU power

connectors on my PSU, sadly i cant remove the GPUs because of the watercooling.

I tried every connector the HDMI, Displayport and DVI.

 

My Motherboard is a Asus z97 gryphon Armor Edition with a 4790k and 2 980tis.

CPU: 4790K (4.8 ghz) | COOLING: Custom Liquid Cooling (240 mm rad) | GPU: GTX 980 ti Superclocked+ (2x)  | MOBO: Gryphon Z97 Armor Edition | RAM: Kingston (4x4 gb 1600 mhz) | SSD: 850 Evo (250 gb) | HDD: Black (1.5 tb) | CASE: Enthoo Evolv | PSU: G2 850 (850 w) | DISPLAYS: Acer XB270HU bprz / Philips 246V5LHAB/27 (3x) | KEYBOARD: Vengeance K60 | MOUSE: Naos 7000 | HEADSEAT: H Wireless / Cloud 2 | For the exact parts visit my PCPartpicker it even includes my Desk and some other stuff.

I'm fairly certain you need to remove the 980's in order to use the onboard GPU signal output.

Weather your GPU's are bricked or not, the system will or rather should still be able to figure out that those two things in the PCI-E slots are display devices and removing the PSU-connectors from your cards while having them inside a PCI-E slot should actually stop your system from even booting up.

@Nord or quote me if you want me to reply back. I don't necessarily check back or subscribe to every topic.

But the systems does indeed boot up and it runs.

I'm sure the system will still see the cards. I know it will still give power. Around 40ish watts per card on stand by.

You could try a cmos reset and see if it will pick up the iGPU if your screen is plugged into it.

Apart from that I think you'll need to remove them.

It's not a race to the bottom.
