PCIe5 Slot Black Screen-Reboot loop

First of all, all components were bought brand new.

During the Nvidia driver installation, my screen goes black and Windows reboots. In the event log I see the entry 1001 BugCheck. Error code 0x00000116 and 0x00000124, as well as WHEA-Logger 16
The system works without a graphics card without problems and also boots normally. In the BIOS I also see all components, temperatures etc. are ok.

Very strange. I installed the graphics card in another computer and it works perfectly.
I installed my old graphics card in the problem computer and it works too.
But as soon as I install the RTX in my new system, the screen goes black at the latest after the Windows login and the system restarts or just stays black. I tried it with a different power supply, but that didn't help either.

In Safe Mode Windows boots normally and I can install the graphics driver there, but as soon as I boot normally it's dark again. I had an RMA on the board, but that didn't help either. Oddly enough, the graphics card only has 1x8 connectors. My guess is that it's drawing too much power through the PCIe slot? But that can't be it either, because the card works in another PC.

I'm at my wit's end.
I can't think of anything else. As soon as the card is in the first PCIe slot it just doesn't work.
But it works in another computer and another card works for me. If I plug the card into another PCIe slot it also works, but it is then only connected with x4 instead of x16. There can't be much left that could not work.

Could it be that the CPU has something? Is the PCIe5 slot on the CPU lane or not? Maybe the graphics card, which only has 8-PIN connectors, is drawing too much power from the MB and the CPU is undervolted. These are all just speculations. I've been fighting with this for weeks.


CPU: Intel Core i9 12900K
RAM: Corsair Dominator Titanium 64GB DDR5-6000
Mainboard: Gigabyte Aorus Pro X Z790
PSU: Corsair Rm1000x with Sleeved Cables
Case: Be Quiet Dark Base Pro 901
GPU: KFA2 RTX4070
SSD: 2x Samsung SSD Evo Pro 990, 2x Samsung SSD Evo Pro 980

The Nvidia card won't be drawing power from the motherboard. At least not much as it gets most of its power through the 8 pin PSU connector.

What you could try is to set the BIOS internal graphics settings to see the PCIe card first, instead of the integrated graphics. It sounds like your PC is forcing the system to use the IGP rather than your shiny new RTX card. You can test this by plugging your monitor into the motherboard graphics port. If I am right, you should not have a black screen when you do this. I am hoping it is just a BIOS setting. Give it a try and let us know how it goes.

By the way, do you know how to change the boot option to use the x16 slot first on the Aorus Pro X?

I will have to check the BIOS on my AORUS when I get home tonight, but someone here will no doubt beat me to an answer. If I am not mistaken, mine is set to PEG, but I will let you know for sure tonight.

Yup. Mine is set to PEG which defaults to the x16 PCIe connector. Although I don't have graphics in my processor, the motherboard option should be the same.

Hope you get it working.

Hi, i found this settings and tried it, but same issue again. Once the GPU is in the x16 nothing works anymore at latest i install the driver.
Can it be that the CPU is faulty? I changed MB, GPU and PSU for testing.

I tried installing the Intel GPU driver followed by the Nvidia GPU driver.
A strange issue occurred: during the extraction of the Nvidia driver to C:, the same black screen problem happened again.
This suggests a potential issue with the CPU right?

Is the PCIe5 slot on the CPU lane or not?

CPU:
- 1 x PCI Express x16 slot, supporting PCIe 5.0 and running at x16 (PCIEX16)

* The PCIEX16 slot shares bandwidth with the M2C_CPU connectors. The PCIEX16 slot operates at up to x8 mode when a device is installed in the M2C_CPU connector.

* The PCIEX16 slot can only support a graphics card or an NVMe SSD. If only one graphics card is to be installed, be sure to install it in the PCIEX16 slot.

I didn't install my M.2 drive in the first slot because I don't want it to share lanes with the GPU. I already disabled XMP in BIOS. Is there anything else I can try? Maybe there's a RAM setting in the BIOS with causing this issue?

Are all your board drivers current ? (ie chipset, etc). First thing I used to do on a new build. It's been a while.
Can you just plain disable the on board graphics via the bios?

I installed almost all drivers for the Mianboard and the CPU. Ive also disabled Integrated Graphics in the BIOS. Same issue.

Sorry, edited post to late. See the one right above
