ok, first of all. All you need is a graphics card that has 3d acceleration. Most graphics cards have that. Right click your desktop, then goto properties, then click the 'settings' tab. On that tab you will see a 'Display:' Now, just tell us the graphics card you have (under display). An alternate way to get here would be to goto your control panel and click "Appearance and Themes', then click 'Display'. And u can get to the 'settings' tab that way.
