Windows 10: Cannot activate Windows 10 Error code: 0xC004C008

I recently built a Pc and got a defective motherboard, everything was fine until my motherboard started BSOD, so I decided to sent it back and ask for a refund since I could't access anything including the BIOS, I could not deactivate my Windows 10 Product Key. I got a new motherboard that works great but now it says in the activation option Error code: 0xC004008. I'm wondering if Microsoft support could help with this issue and deactivate the key from the defective motherboard and transfer the key to this one or if they could provide me a new key or any other way to help fix this problem. Thanks in advance.
