It's not clear to me if the keyboard is working or not. I'd try a PS/2
keyboard if it doesn't and/or unplug and replug the USB one when the
computer is frozen. What happens when you boot without a keyboard?
Put a minimal amount of RAM in and go through all of the modules to see if
one or some of them are broken.
Replace the power supply.
Replace mainboard.
