when i startup my computer its a desktop. I get to the point to where it says press f1 to save changes no usb port is detecting anything therefore its not detecting my keyboard but it still lights up. I have tried resetting the bios plugging the keyboard in multiple ports and yet i have nothing left so i would like to fix this.
