In may 2010 I got a hand-me-down computer from my brother and wanted to wipe his old data to get more sapce on it. I wiped it and put in my old disk a vista one and it wouldn't read it. So I go on Ebay and buy a Windows 7 Ultimate for $30 and activated it. About a month later My motherboard got fried and I got it replaced with the same motherboard and when I log on it says my copy of windows is not genuine and have to buy a new copy of it. Why is this? It said the key was authentic when I used it but now it says its fake? Any way to fix this other than buying a new copy of it? OH almost forgot to add this. I bought my key on Ebay and he E-mailed it to my dad's E-mail. I check for the key and the E=mail is gone.

Hi, 30$ for an Ebay copy tells me that you bought a Technet license, which is not allowed to be sold on ebay. MS blocked the key now. To verifiy my idea, please run the Microsoft Genuine Diagnostics Tool (MGADiag) [1]. Inside the tool click "Copy" and paste the output here.

Hi, Since you replaced the motherboard, the license would consider it as a know computer. I suggest re-activating the system by phone support. You can click Start -> type slui 4 and press Enter -> choose the location -> you will see the phone number and the installation ID. Following the wizard to finish the activation.

As always, an useless wrong reply is marked as answers. 30$ is a Technet copy which is now blocked !!!!"A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/
