ok, as the title says im upgrading to windows 64 bit and i need to know what i have to do in terms of drivers. Video/sound card drivers i can just install after the system has completed installing the OS, but others, like the hard drive cd drive, and other drivers, i am a little confused as the what i need drivers for and when and how i install them. Anyone who can offer me any help would be much appreciated, as well as links to guides and such.
