When the computer is generating a 3D the video card starts working and is being controlled by the driver. So both the hardware and the software of the video card are important.
First make sure your hardware meets the system requirements. In your case I doubt it, because you mention on-board video card, which are not suitable for professional graphic software.

. And here are Graphisoft recommendations for Video Cards
But the driver (the software) controls the hardware and needs to be updated too. Surf to the website of the manufacturer and download the latest driver.
Now you have invested in professional software like ArchiCAD, you need to have the professional equipment to run it. Don't assume that any home-computer can run ArchiCAD.
