I had also solved this problem once. A shopkeeper came to me encountering the same problem. He had changed the I/O chip and keyboards both to solve this problem. But, failed.
When he came to me, what I saw that the wires of I/O chip connecting to the keyboard were damaged. Then by the help of surgical blades, I scratched the edges of the I/O chip and reconnect the wires. Only Asus motherboards are having this type of problem because their PCB are very fragile. ( I didn't need a boardview for this. You can use your multi-meter to watch out the pinouts from keyboard to I/O chip).
