Device not recognized during startup.
Hello, I'm setting up my first PC. I can boot it with the CPU and graphics drivers plus Windows 10 Pro. Most functions are working except that the GPU isn't showing up in Device Manager and I can't capture an image from its output. I'm unsure what to do next, so I'm reaching out here (this is my first time asking for help online). Many components are used secondhand, but I think the issue might be different. The motherboard detects something in the PCIe slot, but I don’t see a clear problem. I can run Windows with the monitor connected to the CPU graphics.
To be honest, I have internet access and can install software (not a Nvidia driver since no GPU is detected). If needed, I can download drivers or apps to resolve this. The fans of the GPU are spinning differently than in other posts, and the lights are on. I’m using a display cable.
I don’t have another GPU for testing or another PC to check the GPU. Currently, there’s no signal—even for BIOS setup—when connecting the monitor to the GPU. In the BIOS (Advanced → System Agent → PCI Express Configuration), I see x16 detected in the first slot, but that’s about it.
My build details: OS – Windows 10 Pro 64-bit; Motherboard – Asus Z490-e; CPU – Intel i9-11900K; GPU – Nvidia RTX 4070; RAM – 2x16 at 3200 MHz (Corsair Vengeance Pro); Power supply – be quiet! 12m 850W; CPU cooler – be quiet! Storage – Fikwot FN955 4TB M.2 PCIe Gen4. The monitor is old but functional after installing basic drivers on my laptop, though performance was poor.
I’ve tried updating the BIOS (latest version 2801 x64) using EZ-Flash and a USB stick. In the BIOS I checked all cables, powered off and restarted, even resetting and re-flashing. I enabled iGPU Multi-Monitor settings, changed the primary display to auto, used a different power cable for the GPU (PCIe 5.0 on both sides plus a 2x8 to 5.0 splitter), and ensured everything was properly installed in the GPU slot and PSU. I also tried updating all Windows updates and graphics drivers.
Please let me know if you need more details or photos—I’m happy to provide them. Thank you!

You inserted the cable into the GPU instead of the motherboard, then linked the PCIe power cables. Just confirming, since many overlook this step...
Would you like to test different cables or switch to HDMI? Which monitor are you using?
B22w-6 from Fujitsu (temporary only). It supports DP, VGA, and DVI, but my GPU only has DP and HDMI. The main issue is that the GPU isn’t detected in the device manager, and I can’t even get a driver because Nvidia claims there’s no compatible GPU.
Well I can try that, but the GPU isn't even detected, I don't only get no image, the system isn't recognising that there is the 4070. And the BIOS doesn't even show, so a windows-setting shouldn't be able to change that. I will update you when I have tested it. Edit: didn't work. The PC is fired up (I hear over my headphones the mouse plugging/unplugging) but I don't have an Image with the GPU. I don't think graphics are the problem, rather than BIOS settings or so, because the GPU isn't detected. Edited March 17, 2024 by pleaseHelpMeThanks Tested the resolution
