Answer» I've finally bought the new CPU [C2D E7500] and GPU [NV GTS 250] for my system and I am PLANNING to install the new components soon. However, I was reading on various reputable computer tech websites that replacing the CPU may warrant a Windows reactivation or reinstallation or so (as apparently the activation key includes a unique identifier of the CPU). Would it be possible to change the CPU from a Pentium D 805 to my new Core 2 Duo E7500 without having to reinstall Windows? I've already checked that the new CPU is compatible with my GIGABYTE motherboard. When I changed a previous PC's cpu from a Duron to an Athlon XP in 2002 I didn't have to reinstall Windows. If, after installing the new CPU, Windows asks for revalidation all you would have to do is call Microsoft and get a new code. Link I've used this method with success...
