The motherboard isn't booting properly without a dedicated GPU connected.
Hello, The system fails to boot unless a dedicated GPU is installed on the motherboard, even though the HDMI cable isn’t connected. The monitor uses an HDMI cable plugged into the motherboard’s port. Integrated graphics are turned on in the BIOS, and the CPU includes a built-in GPU. Removing the video card causes the board to stall—fans spin endlessly without responding. Despite changing CPUs, RAM, SSDs, power supplies, and updating the BIOS, the problem persists. All replaced components are identical. (Note: Swapped parts include the same brand/model.) If you need further assistance, let me know. Thank you! With Video Card 1.mp4 No Video Card 1.mp4 Edited April 4, 2024 by coylegenec Added video clips of issue.
What about monitor cables, did you try other monitor cables? Is this in the recommended slot according to the manual? Since the IGP shares memory with the CPU, I'd make sure that it is. What are the PSUs that you have used? I know this is a dumb question, but someone had to ask, you definitely do NOT have a 12100F? Are you using CSM/Legacy or UEFI?
Hi Tetras, thanks for your response. I've tested various HDMI and VGA cables. The memory is in slot B, which Gigabyte suggests is ideal. I'm using a 380W Antec power supply and a 300W PSU. The CPU isn't the 12100F model. It boots into Windows 11 via the motherboard video output. I'm planning to record a video of the setup. Thanks.
It appears the system starts up correctly without the graphics card connected, but fails entirely when it's removed. This could indicate a BIOS issue, especially if the power supplies are outdated and can't handle low loads properly.
It displays both the Nvidia card and the native Intel integrated graphics.
It's quite unusual. While it's not an original motherboard, there are often configurations that turn off the integrated graphics when a dedicated GPU is present. These settings also affect how the system prioritizes between the integrated and dedicated graphics. It might be that the iGPU isn't being used as the main display driver due to these restrictions. If you've already checked this, plugging in your monitor after booting with the dedicated GPU should reveal whether the integrated graphics are functioning.
Looks like a PSU issue. I plugged in a 500W PSU, and it booted fine without the video card. Since nothing power-hungry plugged into the board, I find it weird that a 380W PSU isn't enough. Anyway, I can stop pulling my hair. Thank you for your help!
