I purchased a eMachines T5230 a while a go, that came preloaded with Windows Vista 32 Bit Premium on it. I recently did a major hardware upgrade including the motherboard and RAM. Upon booting up, it said my Windows key was invalid, even when I typed in the correct key given to me by eMachines when I first bought the computer. I asked for help here, and was told to think about upgrading to Windows 7, which I attempted to do so. However when I try to upgrade to windows 7 it gives me the error that I must be running Windows Vista WITH service pack 1, which I do not have. And because it is not accepting my Vista key anymore, I have been unable to Activate vista to allow me to download SP1. I am unsure of why all this hassle is occurring and am quite displeased with it.
