Can Not run 3D samples

Greeting;
I am getting back into programming and when I tried to run a 3D sample, a displayed error came up.Unable
to set graphics mode.I have Windows 2000 .What am I doing wrong?
I also did several downloads from the CD and it still does not work.
Thank You
David

Run the DirectX app "dxdiag.exe". (go to the execution prompt and enter dxdiag). Make the 3D tests. Tell us if your machine is capable of using hardware accelerated 3D graphics at all.

If it turns out that you do have 3d graphics capability (as per jfk's suggestion), try also the GfxMode3DExists( width, height, depth) command to see if the width, height, and depth stats the sample is attempting are valid for your video card, i.e. (absurd example, here) if the sample asks for 292 x 901x99, the mode may simply not exist on your card.

Greeting;
As you as suggested. It worked.

Thank You
