Motherboard
The VGA Q-LED latches when the UEFI/BIOS fails to complete the handshake with the Graphics Output Protocol (GOP) on the GPU. On the Z790 platform, this is primarily an initialization failure caused by outdated firmware that lacks the microcode to properly negotiate PCIe lane allocation with 14th Generation Intel processors or high-bandwidth DisplayPort 1.4/2.0 devices. Updating the BIOS via the FlashBack interface reconciles these communication protocols and extends the handshake timeout window.
