Hello, my motherboard had q-code 40, I updated the bios and after that it doesn't work, can you help me? It does not starting, the lights on the motherboard are flashing.
May I ask if you have updated the Intel ME to the corresponding version in the BIOS? For example, the latest BIOS version of the ROG MAXIMUS XII EXTREME is 2701, which requires updating the Intel ME to 22.214.171.1249V1.1.
Is the flashing light you described on the motherboard pointing to the Q-LED light that is constantly on?
If so, please refer to [Motherboard] ASUS motherboard troubleshooting via Q-LED indicators to troubleshoot the VGA Q-LED light issue.
Meanwhile, we suggest you refer to [Motherboard] Troubleshooting - No Power/No Boot/No Display and test with minimal components to isolate the possible cause.
