The RAM, CPU and motherboard are all new parts, and USBs re enabled in BIOS. The keyboard works in BIOS, and sometimes the lights on my keybord abd mouse willl be lit, but once the OS has booted, neither work. I have not installed the motherboard drivers because this has prevented me from doing so.

Can you try a PS2 set to install the drivers.
I could only find a mouse, and it doesn't appear to be working either.
Scratch that, after a restart or two it's working, will report after drivers are installed.
