A COLLABORATOR THAT HELPS ME IN MY CASE. I HAVE A PC WITH A MOTHER CARD AS DESCRIBED IN WHICH IT STARTS WHEN THE SOURCE IS STARTED, I HAVE DISCONNECTED ALL THE ELEMENTS OF THE FRONT PANEL AND DISCONNECT THE MICRO CONNECTOR AND EQUALLY WHEN UNDERTAKING THE SOURCE START THE MICRO FAN DIRECTLY. WHAT DO YOU BELIEVE YOU COULD BE PASSING ON THIS TEAM TO START SO? EVEN IF YOU FORGET TO MENTION THAT WITH ALL THEIR ITEMS CONNECTED THE PLATE LED INDICATES THAT EVERYTHING IS WELL EVEN IF YOU DON'T BOOT VIDEO.
