If I understand what you have written, you removed a hard drive from a newer PC, and put an older hard drive in its place? Is it rejecting your sign in info or is there no input when you try? I'm sorry, but I didn't understand what you meant about "newer pc wireless older was broadband." Under your avatar it says your OS is 2000, being 13 years old. You put a 13 year old OS along with old, outdated drivers and files into a newer PC? I would say the problem is hardware/software incompatibility.
Wait, ok...you meant the older PC was broadband (Ethernet cable) and the newer was wireless. I don't see what that would have to do with being unable to log in to Windows.
