I get this problem when i updated my graphics card

[My specs my Processor Intel core 2 duo and my graphics card ati radeon hd 3450 my OS Windows 7 64-bit 4gb ram] updated drivers rebooted i used to have a intel q33 chipset family integrated graphics card and sims 2 worked with that but other games did not work with that card like South park Stick of truth and portal 2 but if anybody has a fix for this let me know

Read this post http://www.modthesims.info/wiki.php...:Graphics_Cards and notice:
"Also, try deleting My documents/ EA Games/ The Sims2/ Config/ userprops.xml. This contains details about your previous graphics settings and will be refreshed by the game when you next run it"
BUT:
Deleting userProps.xml can cause all your Maxis made 'hoods to revert to their default fresh-out-of-the-box states -so:*backup*your Neighborhoods folder before deleting UserProps.xml so you can restore it if this happens.

Deleting userProps.xml wont work and the link is a 404but the computer that has the ati hd 3450 is not hooked up to the internet i'm posting this on a different computer and the only sims game i can play is the sims complete collection and the original sims but not sims 2

Normally the pc makes a autobackup (I don't know what it exactly is in English) before installing a driver. You can try that.
You can also go to the ati site and download a previous driver. That worked for my nvidia card.
If I understood correctly your pc has a dual card? Then you can decide which program to run on which card (eg my laptop has both an intel and nvidia card). That can be a solution too.
I don't know how to help further. I have had bad experience with ati cares so for graphic games I swear on nvidia.

I fixed it by getting it to run in windowed mode

The game runs better in a lower resolution, cause when it first came out, the standard resolution was lower than it is now.
So playing in Windowed mode is recommended and it does makes sence it fixed your problem.
