PC activates without GPU, yet fails to start when GPU is present.
The computer functions properly without a GPU, but fails when the Intel Arc A770 is present. I've tried various GPUs in the system, yet none have worked either. Here are the specifications: Motherboard: MSI Pro Z790-P, CPU: Intel i7-14700k, GPU: Intel ARC A770, RAM: 2x16 GB DDR5-6000 CL32-38-38-96, SSD: Inland 2TB, PSU: PowerSpec 650W 80 Plus Gold. Alternate GPUs tested include EVGA RTX 2070 Super and XFX Radeon HD 5770. The issue is that the PC doesn't power on at all—no fans spin, and nothing appears on the screen. Some lights on the GPU and motherboard are visible, but that's it.
Clean out the PCIe slot, possibly containing dust, hair, or debris (consider inspecting the pins during this process), then attempt to boot without RAM, adding it gradually while powering up between changes, finally doing all of this with the motherboard's Wi-Fi disabled.
I didn't attempt to blow out the PCIe slots, but I tried using one of the other slots. That didn't resolve the problem. Regarding the RAM, the system operates smoothly without a GPU installed, so altering it might not make much difference—please let me know if you're mistaken.
Don't doubt my point, but I just said this because based on my past experiences with getting PCs to boot after they were on the operating table—meaning they had to be forced to start—I believe this method could be effective. It's one of those possibilities to explore through process of elimination and testing.
If the machine is running ok without a GPU and you have tried several GPUs, then I am inclined to think that your power supply is being loaded down by the addition of any GPU. Try to borrow another CPU for testing purposes. But there's a possibility of it being the motherboard or something else. It would be good to eliminate the power supply first and then troubleshoot further if it doesn't resolve the problem
Did you look at the first option in the bios? You might need to adjust it each time you move from a booting success without a GPU to a boot issue with the GPU. This would only stop the display and let the PC start, but I don’t want you to get mixed up about that.
