You may have to reinstall the OS after doing that. Windows can sometimes freak out when you go to a different chipset that isn't similar enough to the one it has drivers for.
If you're lucky, that won't happen, Windows will boot up and you just need to install the drivers for all your motherboard devices and reactivate Windows. If Windows doesn't boot up successfully, you'll likely have to reinstall the OS.
that happened.. windows detected unrecoverable boot error and I reinstalled windows.. thanks for your help
