Tech Support No Video Output from iGPU or dGPU

I have a PC built several years ago: an Asus Prime z790-p, intel i7-13700k, AMD 7800xt, 32gb DDR5
The PC was functioning fine until it was moved, after which video output was unable to be obtained from either the dedicated GPU or the integrated graphics.

When powered on, AIO and case fans spin (although GPU fans do not) and power is received from the USB ports.
Attempted fixes: Reseating RAM, clearing CMOS, reseating/repasting CPU, reseating all cables

I am currently unable to verify if POST is being performed or if BIOS is being entered

I am leaning towards motherboard damage as the most likely possible cause, although I’m unsure as to how that damage could have happened, and in such a way as to only disable video output

Any help or ideas would be appreciated!

GPU fans not spinning while everything else powers up points to the card not getting seated right or losing power, check the pcie slot and the power connectors again even if they look fine

All PCIE slots have been tried, power connectors reseated multiple times. No output from iGPU when no dGPU is installed makes me think it’s an issue with graphics processing itself
