Has anyone else noticed that when they installed any of the sims games (I have all minus the stuff packs) that their computer acts up a little. For example. Without the games, I didn't have many issues with videos or pictures. When I downloaded it again, I noticed these problems popped up again. If I go to a website like YouTube, the videos never load properly. If I got to something like Myspace, some of the pictures show up distorted and discolored if that makes sense. Anyone else witness anything similar. I don't have any hack conflicts...the game runs fine when I play, but when it's not running and I'm just surfing the net or something, I come across these problems. Also, websites start to give me "error codes" like Message Authentication Code etc. etc.
Any help? Greatly appreciated
