Graphics Processing Unit (GPU)
The GPU is the primary device the VGA light monitors. Failure occurs when the GPU's Video BIOS (VBIOS) fails to communicate with the motherboard's UEFI via the Graphics Output Protocol (GOP). This can be a result of internal component failure or an incompatible firmware version that prevents the motherboard from recognizing the device during the boot sequence.

ATX Power Supply Unit (PSU)
The GPU requires a specific voltage ramp-up on the +12V rail during the initialization phase. If the PSU fails to deliver stable amperage or if the PCIe power connectors have high contact resistance, the GPU will not power its onboard logic controller fast enough to respond to the motherboard's polling, resulting in a VGA diagnostic hang.

PCIe Riser Cable (Gen 4.0/5.0)
On enthusiast X670 builds, vertical mounting is common. If a lower-specification riser cable is used, the high-frequency differential signals required for PCIe 4.0/5.0 will suffer from excessive EMI or impedance mismatch, causing the link training to fail and the motherboard to trigger the VGA error light due to corrupted data packets.
