I am decent with the programming of a computer but not the hardware. I have a Dell Dimension 3000 and I really like it. However, I really like the Age of Empires games and I recently bought the 3rd one and my computer will not run it due to sound and video card issues as well as virtual memory. I'm not quite sure what virtual memory is or how it affects the computer proccessing. How can I remedy my problem of not being able to play my game?
