You're graphic chip is below specs. You need at least 128 MB of dedicated memory, you only have 64 MB
Try lowering your graphic settings and turn off mirror reflections.
Also update your graphics driver. They are outdated.
It is weird that you have to reinstall the game to open though.
What do you mean by when I minimize the laucher it closes ? Does it crash ?
You can also try the factory reset described in this post: http://answers.ea.com/t5/The-Sims-3/FAQ-Troubleshooting-Steps/td-p/714/
Yes it does crash, but only started last after the last time I re installed.
What happens when you try to re-start after the crash ? Do you get any error messages ?
no, I can open it normally...
So you can start the game now but it crashes right away (sorry, confused).
Did you try lowering your settngs ?
