Do you actually have 2 keyboards plugged in? Might want to unplug one if you do, if not, unplug everything except the keyboard and see if that helps.
Nah, my computer has always done this with Razer products. When I have my Keyboard and Mouse plugged in it says I have 4 keyboards and 2 mice plugged in. No idea why. Have tried with everything (including all sata stuff) unplugged except the keyboard and it just goes to that same "press F1" screen
