Don't 'double post', which is posting back-to-back. I'd prefer you just modify your post if it's still the last one. The "modify" button is located in the top right of every post you make.
How to find what video card you have:
1. Click start, select run, then type in dxdiag in the box that opens. Hit enter, then a larger box will popup.
2. Click the tab at the top that says "display"
3. Find the device name, and post it here.
