I have been having some performance issues with my Sims 2 game, including the fact that the background inside the house is often messed up unless I move the mouse around. It seems to be pulling the background from outside for some reason. The main problem I am having is that my computer keeps freezing whenever my people become best friends and the smiley faces float up. This also happens when there are any cut scenes (ie first kiss). When I restart my computer it says that mobility radeon 9000 has experienced a serious error. I thought that maybe I needed to update my drivers, but when I go to the ati site and download the new drivers I can download them fine, but it won't let me install them. It says that it can't find the original hardware. I don't understand this, because when I look under display it definitely says my video driver is mobility radeon 9000. Thanks for any help!
