Installing NVIDIA drivers on 64bit Windows 8

I upgraded a Sony laptop from Windows 7 to Windows 8 but the upgrade did not detect the Nvidia graphics chipset. I grabbed the latest Windows 8 64bit Nvidia driver from http://www.laptopvideo2go.com/ but the installer failed. It turns out that 64 bit Windows 8 will not install a driver unless it’s signed. You can disable signature checking by :

  • Windows Key + C to bring up charms menu
  • Click “Settings”
  • Click “Change PC Settings”
  • Click “General”
  • Under Advanced Start-up click the “Restart Now” button
  • Click “Troubleshoot”
  • Click “Advanced Options”
  • Click “Start-up Settings”
  • Click “Restart” button
  • Press option 7 – Disable driver signature enforcement
  • You can now install your un-signed 64bit driver
