In this video I show you how to replace your motherboard and it's components, including the CPU and RAM. However I run into a problem re-activating Windows 10 (upgraded from Windows 7)
Activation issue starts at 18:32 not much you can do besides re-install your licensed copy of the OS (say Windows 7) or purchase Windows 10. UPDATE: After the anniversary update Microsoft fixed many of the activation issues. Now as long as your Win10 key was attached to your Microsoft account you should be able to re-activate by logging back in with that MS account.
