I cannot get my keyboard to work when I boot up. I just got a INTEL D915GAG D915PSY LGA SOCKET 775 to replace the same motherboard I had that died. When I boot up the lights on the keyboard flash and then I get the message at the bottom of the screen that says press f2 to enter setup press f12 to boot from network. Pressing the buttons does nothing. There is also a message on the screen that says USB Legacy ....... Detected and Legacy Keyboard .........Detected. I have tried 3 different keyboards; two ps/2 and one usb. None of them work. I removed the battery to reset BIOS but this did nothing. I also removed all hardware except 1 stick of ram and booted as "bare bones" as possible, still no luck. I am completely baffled. Anyone have any ides?
