Ok ... You have just bought Sims 3 for PC and installed it and everything was fine until it loads. The graphics card is "unsuggested" and not with the game that we as Best Buy and they told me I needed more memory work ... So we bought 1 GB. Anyway, we re-installed and the same problem! Then I wondered if I could go back and buy a card of 1 GB of video memory adds to the computer.
