Windows Activation failed after i replaced my motherboard.

Hi,

I recently purchased a laptop with win8.1 and upgraded it to win10. I found that my Laptop's motherboard is bit faulty and was causing some problems with the hardware so i replaced it from my manufacturer LENOVO with a new one as it was still under warranty.
After i switched back on my laptop after replacing the motherboard an icon began to show up at the bottom right corner of the screen saying "Activate Windows". I went to windows settings and tried to reactivate it with the product key (which i learned how
to get it from a youtube tutorial) but it says Activation failed with error code " 0x803f7001 " .

Does changing my motherboard affect my OS and if so, how do i rectify it and activate my windows back. Im currently in Win10(yet to be activated) version of my purchased Laptop.

Laptop model is Lenovo G50-70

Please someone help me out with possible solutions.

Thank you in advance.

 

Can't reactivate Windows 10 after faulty motherboard replaced

Hi,

I had to replace my motherboard as it was faulty. I only built the system about 2 months ago.

When I try to activate Windows 10 it just says I need to buy another product key. Even after running the troubleshooter it just says "We can’t reactivate Windows on this device. Try again later. " and helpfully suggest I buy Windows 10 again.

How can I get this activated?

Thanks

 

Reactivating Windows 10 after replacing faulty motherboard

Spilt liquid on my motherboard so had to replace it. Ive now installed the replacement, but windows is no longer activated.

Ive run through the activation troubleshooter and followed the link for "I recently changed hardware on this device"

I selected my PC from the list of my Windows 10 devices, checked "This is the device that Im using at the moment" and clicked the Activate button, but get -

"Unable to activate Windows

We can’t reactivate Windows on this device. Try again later. "

I've now been trying for 24 hours but always get the same message
