I wouldn't recommend using Driver Booster to update drivers because in most of the cases it does more damage. I've checked the official website, and it appears, there are drivers for all their graphical drivers.
Access the following page to download them: http://www.c3technology.com.br/2013/suporte_drive_faq.php?d=all
Secondly, disable Driver Enforcement and then install the application/drivers because if the drivers are unsigned, Windows will refuse to install them.
Disable Driver Enforcement: Start > Settings > Update and Recovery > Recovery > Advanced Startup > Restart > Troubleshoot > Advanced options > Startup Settings > Press key 7 > Restart.
