Re: Sims 3 crashes randomly
@lilaaaaaaaaaaali First of all, please undo the change you made to try to force the game to use more RAM. This is actually useless advice based on bad information and a misunderstanding of the value it references. Sims 3 has been Large Address Aware since 2010, meaning it can use about 3.7 GB RAM (4 minus some overhead) already. The value people are told to change is actually the size of the game's script heap, and it's 20 GB, not 2. (Count the zeroes.) Point is, please reverse the change.
For the crashing, have you tested in a clean user folder yet? If not, please do so now: move the entire Sims 3 folder out of Documents > Electronic Arts and onto your desktop, and when you launch the game, a new folder will spawn with no content. Don't add anything to it yet; just start a new save and see whether the game crashes. If you want, you can just build; you can transfer a partial or complete build to your main user folder later if you'd like, so this doesn't have to be a waste of time.
If the game crashes in the new folder, please run a dxdiag and attach it to a post.
