    HalloThien Bui,
    Ich habe ein zweites identisches Board, Bios mit sauberem ME, aufgenommen.
    10 = Diagnose-LEDs 1-4
    AC Eingangsspannung (Erhaltungsladung vorhanden)
    Stromversorgung DC Ausgangsspannung
    GPU funktioniert
    Anzeigefeld ist angeschlossen
    Ich habe ein Bild gemacht, beide Boards erkennen die GPU nicht.


    Kannst du bitte mit Bios klären, mir zu helfen.

    freundliche Grüße
