Hello Savina, thanks for joining the Intel Community.
The latest graphics driver available for the HD4400 is version 3958 Intel® Download Center , but the drivers we provided are generic drivers. We recommend customer to use only the graphics drivers provided by the system manufacture, in your case will be DELL.
OEMs manufactures make many customizations to the drivers and if you install generic drivers, they could overwrite those customizations.
Try installing this driver version and let me know if it resolves your issue.
