Re: Sims 2 DVD Rom crashing
One instance where I noticed this in my game was a failed base game patch, which corrupted one of the core game files and prevented lots from loading. You have physical copies of the game, so that might be a possible cause of the issue.
Since you have all Expansion Packs, please let me know if you updated each and every one of them, including the base game. For every patch, you should have got a message that says it was completed successfully. Please note that not all patches are included on disks, and you might have to look for them on sites such as Mod the Sims or SimsVIP.
To check if your base game patch has crashed, please check the base game's objects.package file; that one usually gets corrupted during a failed update. It should be located in C:\Program Files (x86)\EA Games\The Sims 2\TSData\Res\Objects\ if you installed the game in the default location. There should only be one file in that folder.
Aside from this, let me know if you have used Graphics Rules Maker, and, if you did, which settings you applied.
