Facts: I have an HP G60 I bought new originally from Costco some time ago. It has Win 7. The computer died, I bought another parts computer with a damaged screen. I swapped the screen and the Hard Drive to the parts computer. Now 6 months later I suddenly get a WGA error. I contact M$ and they say my Serial is valid and I need to contact HP. HP says out of warranty and we'll be glad to help for a price. What the heck?!!!! I paid for this; I'm not paying again! Any idea on how to proceed short of a hacked OS?
