Accelerated 3D Graphics card
Some programs require an accelerated 3D graphics card to run properly. Some programs run very slowly or not at all unless Microsoft DirectDraw or Direct3D hardware acceleration is available. To check your system to see if your computer meets this requirement, click on Start, then Run, and in the Run field type "dxdiag" and click "Ok."
On the "DirectX Diagnostic Tool" display page, click on the Display tab, and look under DirectX Features to see whether DirectDraw, Direct3D, or AGP Texture acceleration is marked "Not Available." If so, you might consider upgrading your hardware.
