simsgamer2life Have you tested without your Mods folder? There's no need to save your progress, but it's important to at least establish whether the game crashes without any mods or custom content at all.
Additionally, is there any pattern to when the crashes happen, for example in CAS or when your sims try to travel?
If the game crashes with no mods or cc, please run a dxdiag and attach it to a post. Hit Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop. From there, you can attach it to a reply using the camera (Insert Media) icon with the other formatting options.
