What AMD Driver should I use?
It is best to use Toshiba's APU Graphic driver since they are customized to be 100% compatible with your laptop. But if they are very out-dated then you can use AMD generic laptop drivers which should work but may not use all the features of your laptop.
Make sure all of your Laptop drivers are up to date including the latest BIOS/UEFI version from Toshiba Support. Also Windows must be fully updated via Windows Update for the latest AMD Drivers to work correctly.
This is where you can download all of your Toshiba's laptop drivers and BIOS: SATELLITE C70D-B Support | Dynabook
