How do you make the 2 pin connection on the K7S5A mobo accept the connection of the 3 pin connector from the case. The 3 pin receptor has a green wire on one end and a white wire on the other end and no wire in the middle...so therefore one of the wires is not even making a connection. I have 2 different cases that have the exact same Power LED pin connection. Any ideas would be appeciated.
