Windows XP activation
just had my hard drive fail on me about a week ago. So i replaced the hard drive, processor, motherboard, and graphics card. I am stunned by the performance increase!! But there is one little problem, the activation code for windows XP constantly says thats its invalid, And trust me its typed EXACTLY from the product key tag that came on my computer. I've typed it, my mom has typed it, my girlfriend, her secret lover, the mail man, and my math teacher have all typed it and every time it said it was the wrong code. I want to know if it isnt working beceause i am using a different set of components than what my computer origionally came with (it WAS a gateway back in the day before i replaced everything). I have tried searching through microsft's help and support but havent found anything to help. i tried Gateway but since none of the components are stock from what they sold me they cant help.
If my only option is buying a new XP Copy then could some one tell me about any good deals on windows XP 64bit?
Thanks EVERYONE!! for even reading this and taking your time to help me out no matter how stupid my questions.
