sony downloads

Sony have just hit me with a bombshell. I have a Sony Vaio AllInOne PC, the 250GB hard drive failed, so I fitted a 1TB hard drive, reinstalled Windows Vista, tried to install the download graphics, ethernet, wireless, etc, but nothing works. Their downloads only work on the original drive. The PC is fixed to only allow the original hard drive to work in Windows. Does anyone have a solution to this please?
