As an elderly, retired gentleman, I am building a computer system for my 19 year old granddaughters christmas, using a gigabyte GA-7DXE motherboard. In the motherboard, are 2 cable USB ports at the front of the motherboard. Although I have perused the manual several times, and have found the correct socket onto which the cables are connected, on the motherboard, my difficulty is that there are wires coloured; white; yellow; orange; black; blue; green; purple; red; and grey to connect to this socket. NINE wires in all, buth there are only EIGHT pins in the socket. I could obviously leave this cable unconnected, as the system still works fine, but I really would like it connected to complete the job fully. Can anyone help and tell me the correct procedure about these nine wires. Thanks.
