These aren't actual error lights. They indicate the section of the POST process you're in. If it freezes on one, that's where you should begin troubleshooting. From your video, it seems to move smoothly to the Boot stage before stopping?
If the lights dim and the machine remains active, it indicates a POST process is complete and the monitor is no longer needed. Confirm your display is linked to the GPU rather than the motherboard. Since your CPU lacks an integrated graphics unit, the motherboard connections won't function properly. The final step to verify is checking the GPU connection, which requires using another device for testing. Ensure the monitor is attached to the lower ports.
