The appropriate drivers for your system should be provided by your computer manufacturer, here you should be able to download the drivers manually ASRock > P55 Deluxe3 and this utility ASRock Live Update & App Shop is designed for system update and software downloading, you can also go to Drivers & Software and find the graphics driver.
Yes sure, I can download the outdated (although functional of course) drivers manually from the manufracturer site.
But what's the point of the Intel Driver Update Utility then?? Moreover my motherboard is not supported by the ASRock Live Update & App Shop as one can easily see when checking the "Support List" at the bottom of your link.
It is a utility that identifies new drivers available for your Intel components and provides the option to automatically install them. Intel provides generic versions of drivers for general purposes. Intel recommends you contact your computer manufacturer for the latest system specific updates and technical support information.
The Intel component on your system is the processor, so in this case the utility will help you to identify new generic drivers available for your graphics controller, the rest of components drivers should be provided by their specific manufacturer since it is possible that your computer manufacturer may have altered the features, incorporated customizations, or made other changes to their drivers.
