thank you so so much for your support , everything back working normal, all the usb ports are working fine , but i can't use the cpu HDMI port anymore , i'm now using the graphic card HDMI port and the pc is slower now.
i take out the Black connector and leave it hangingand then i start it, but same problem everything start and no image and to shut it down i stay clicking in the button until it shut it down.
as you can see in the photo the first pin pulled out. and when i start the pc it start then stop , and stay like that, start and stop automatically!! and no image in the screen !
