You don't have the correct video driver installed, i.e. you probably have the windows provided driver, but you need a fully featured one direct from the GPU manufacturer (Intel, AMD, or Nvidia).

Post the full dxdiag file if you need help finding it.

Here is my DXDiag output, hope this provides more clues on what's going on

Thanks again,

To clarify what gerbil said, you need a new or update your graphic card.
