You have not posted your machine details or what version of ArchiCAD you are having this problem with... and not only the version, but the build number, and if educational, trial, start or full/professional.
As to your machine, the details of your graphics card are essential. It is possible that your card is simply not OpenGL compatible. (I had a compatible ATI card in one of my other computers, and due to some hardware overheating issue, it was no longer able to run OpenGL and had to be replaced.)
Cheers,
