Thanks for the answer Grumpy_Mike. I have no clue on what's going on.
The only pictures I have are very low quality pictures from a guy that dissasembled the board.
I discovered a new clue: When I use the nearby usb the board is not stable at all. So this problem should be related to the USB power, the back usb works as expected. Too bad that customs charged me a lot for this x86 board, so getting help from the store will be very hard and expensive.
