Hello Scatghadi, thanks for joining the Intel Community.
We always recommend customers to download and install the drivers provided by the system manufacture, in your case from Toshiba, since our drivers are generic drivers and sometimes these cannot be installed on other systems or the installation of them could overwrite their customizations and possibly change the functionality of the graphics.
You can try to install ours by forcing the installation and performing manual procedure, however I cannot assure you they are going to work as expected.
See here for instructions: Graphics Drivers — Computer manufacturer graphics driver detected
The latest driver available for the Intel® Graphics Media Accelerator Driver for G41 Express Chipset from our side is version 2869
You can give it try, however we cannot assure you it will work as expected.
