Windows 7 COA/Key code failed on a new motherboard&CPU

[Guest escapedaweb]

Hi all,

 

 

I bought a retail copy of Windows 7 Upgrade few years ago. Since then my old PC broke down, and recently, I built a new PC--new motherboard, CPU, etc. I used the retail copy of Windows 7 Upgrade DVD to full install of the OS on a blank hard drive.

 

 

Everything runs great until I punched in my key code to activate my PC. I got a message which informed me that the key code is not valid.

 

 

Am I getting this invalid key code message because I used my Upgrade Windows 7 DVD? If this were to be true, should I buy a FULL version Windows 7 DVD and use its Key code to activate my PC?

 

 

Thanks for any help on this.
