Won't boot into Windows after Hardware Upgrade

[MinorMIx]

Hi all, my computer is not booting into Windows 7 after I had just replaced the motherboard and CPU, anyone know what I need to do?

You need to reinstall Windows. Windows uses a hardware profile and installs the drivers needed for the specific parts in the machine at the time of install. Since the parts are not the same, Windows will not boot. If you have an OEM version of Windows that came with a pre-built machine you will have to purchase a new copy of Windows. If it was an upgrade or retail version you should be okay to just reinstall without activation issues.
