I have no idea what the problem may be but I saw a laptop yesterday where there was no 3D when using the vectorial engine.
I wasn't able to play with it long enough to figure out what the actual problem was.
Try switching between vectorial and OpenGL to see if that makes a difference.
Using OpenGL worked on the laptop.
Also test the regular culprits.
Try using different Model View Options, Renovation Filters and Graphic Override combinations to see if that makes any difference.
