If you could post your DXDIAG information so that we can take a look. Just follow the steps below.
1. From Windows, click Start -> Run. (Vista) Start Search
2. In the Open box, type "dxdiag" (without the quotes) and click OK.
3. Once the DXDIAG file is open, click on the "save all information...”
button.
