My friend has the original PowerBook G4 17". She's a big fan of the Sims, and just got The Sims 2 and Mac OS 10.4 yesterday. She can't figure out what's wrong with the game because certain menus don't show up. Is it her video card? She wants to get a new computer, although she thinks the only way to make it work is to buy a PC, but she doesn't want to do that. Thanks in advance.
