Question PC turns on when GPU isn't installed, but doesn't turn on when there is a GPU installed.

The computer is up and running just fine when there is no GPU installed, but when the Intel Arc A770 is installed the PC doesn't turn on. I have tested different GPUs in the system, but none of the GPUs worked either. Specs: Motherboard: MSI Pro Z790-P WIFI 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: EVGA RTX 2070 Super, XFX Radeon HD 5770

The problem is that the computer doesn't turn on at all. The fans don't spin, and nothing is displayed. Some lights turn on on the GPU and motherboard, but that is all.

Blow out the PCIe slot, might be some dust or hair or debris in there,( might want to check the pins while doing that) then try booting without the ram, then adding ram one by one powering up in between changes, lastly do all of that with the wifi on the motherboard turned off.

Other than that, might get some other input from other members.

I didn't try blowing out the PCIe slots, but I did try using one of the other PCIe slots. That did not fix the issue though. As for the RAM, the system does function perfectly fine when there is no GPU installed, so I am not sure if messing with the RAM would change much (if I am wrong about this don't hesitate to correct me).

Don't think your wrong about this, but I just mentioned that because in the past of my own experiences with getting pc's to boot after they had been on the operating table so to say they had to be forced to boot not expected to boot, this is one of those methods to do just that, process of elimination, try and test.

Well, and keep in mind that only works if there is not actually a hardware fault.

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

I meant another PSU, not CPU.

Did you check the display 1st option in the bios, might need to change that every time you go from the booting success without a GPU to the boot issue with the GPU's, but that would only cause the display not to work and the pc would actually be booting, I'm hoping your not getting confused by that fact.
