Usually there are only software conflicts with 64-bit Vista right and not hardware? Just want to make sure because I want to upgrade from 32-bit to 64-bit, thank you.
I myself have had problems with only one program. That program being Nintendo's software for the wifi usb adapter. They don't support Vista 64 bit and the compatibility mode makes no difference. Even when messing with the signed/unsigned drivers it still will not work. However, that's not really a problem with 64 bit as it is with Nintendo.
