Everytime I boot this Computer it comes up with Keyboard error and makes an irritaing clicking sound and will not go further. I tried four different keyboards that worked on other computers with the same results. And yes I have tried both PS2 connectors. It used to work perfectly ok. before and started doing thisout of the blue. This is on Soyo 6BA motherboard. If it comes to it can I use a USB keyboard or do I need a PS2 one to enable a USB support in the BIOS?
