GPU not showing image

[JamesF]

Howdy! 

 

Been building PC’s for myself and friends for 15 years and today i have the first issue i cannot solve by myself. been breaking my head over it for hours.

 

3 weeks ago my CPU’s AiO pump broke and it got shipped for repairs. today i revieved a new one: NZXT Kraken 280.

 

This morning, my PC worked just fine with the Intel Stock cooler on it. Now with the new AiO installed, My Displays don’t get a picture from my GPU. I can post and use Windows or BIOS just fine connected to the integrated Graphics via Motherboard.

 

these are my specs:

 

Intel Core i7 12700k

RTX 4070

Asrock Z690-ITX

2x 16GB HyperX Fury 3000 Mhz

Corsair RM750W

NZXT H210 Case

NZXT Kraken 280

 

I updated the BIOS

I reset the BIOS

I tried other cables, display and connectors

I reinstalled the drivers

I reconnected the GPU (Fans spinning, lights are on)

 

All im all it boils down to this:

 

1. This morning everything worked

2. PC works via HDMI on Motherboard

3. I didn’t touch the GPU or CPU

 

Does anyone have any idea what i can do…

 

i don’t have a second GPU or System to check. I have reapplied thermal Paste

 

Thank you very much in advance!

Did you check the mounting pressure? It could be too much, uneven, or not enough.

How would I check this? and should that still make my PC boot via motherboard. The AiO is on the CPU, not the GPU

Having the cooler too tight can cause some warping to the cpu or the board which could have an effect on some connections. Use the proper shims or spacers recommended for your application along with the rest of the correct hardware for your cpu cooler to ensure the correct fitment. 

 

Don't know for sure if it will solve the issue, but it worked fine with a little stock cooler which is designed to fit with a certain amount of pressure that Intel paid engineers to figure out.

Just tried working with different pressures. to lose, to tight & some in between. did about 5 different fits. but still the same issue

 

usually just tighten them up till a get resistance and then go just a bit more

Ok we tried. Let's hope the GPU did not just fail for no reason. See if you can get your hands a gpu to use for testing, something dirt cheap and known to work.

Alright, so situation isn’t getting better: i tried a different GPU, didn’t work. I ordered a new motherboard & the issue persists there too, with 3 different GPU’s

 

And still going trough onboard graphics, no problem launching windows

Do either graphics card show up in Windows Device Manager>Display Adapters? Do you see anything there besides the Intel UHD 770?

In your BIOS, try to force PCIE link speed to gen 3 or gen 4. 

 

When the old AIO broke, what happened? Did the pump just stop spinning, or did it leak fluid?

Yeah the pump just stopped spinning.

 

In device Manager, only the UHD 770 shows up. I’ll try that with gen 3, thanks!

Any chance this could be CPU related? Different PSU & the PCI-E 3 didn’t help. everything else now is basically new

Clear CMOS. Check power cables. Plug display back in gpu.

Done so, unfortunately still the same. thank you
