|If it's crashing out in or before BIOS arrives then you have a "hardware fault" so no fiddling around with settings will help. BIOS has to work before windows can start.|
If it's not something along the lines of what I mentioned in #1 then maybe the keyboard itself is faulty or something was zapped during the keyboard installation. If you happened to leave the main battery in during keyboard installation then zapping is possible.
Always pop back and let us know the outcome - thanks
