You've literally posted nothing to help us know what specific hardware you have.
Assuming you're on Win7,
Start, type dxdiag, press enter. Save all information to textfile and post here with a spoiler tag. If you're on a previous version of Windows, start>run>dxdiag will work.
Thanks for telling me, I found what you should need to know. I dont know how to do spoiler tags though but here it is.
