ACCESS_VIOLATION writing address 0x00000000

@TheRetardedKidMF  The issue is clear from the crash log:

Total virtual memory: 4095 Mb
Free virtual memory: 66 Mb

The word "virtual" here is a misnomer: the log is referencing the memory Sims 3 can use.  It's a 32-bit app, so 4 GB is the limit, and somehow it used almost all of that just trying to load.

Have you added any mods or custom content?  If so, please move the entire Sims 3 folder out of Documents\Electronic Arts and onto yoru desktop.  If you've tweaked any game files, please undo the change(s), or else use Steam's repair function (Settings > Properties > Local Files > Verify the integrity of the local files).  The game should run fine on Steam out of the box, so to speak, other than the need to manually limit in-game framerates on anything resembling a gaming graphics card.  Let me know if you need help with that.

If the above doesn't make a difference, please run a dxdiag and attach it to a post.

The crash log lists Windows Vista because it hasn't been updated in a very long time, since long before Windows 10 existed.  It's not indicative of a problem.

Nope, no custom content, just the base game and all of the addons. Tried Steam's "verify integrity" option but it didn't find any files missing.

I have the DxDiag report linked if you want to check it out.

@TheRetardedKidMF  Both of your hard drives are pretty low on space, although that shouldn't cause this particular error; it's just something to keep an eye on.  Your computer's page file was also being heavily used when you ran the dxdiag and when Sims 3 generated that crash log, so you might have some extra junk running in the background that isn't helping.

First though, try uninstalling and reinstalling VC++ 2005, which Sims 3 uses.  Hit Windows key-i, select Apps, scroll down to the Microsoft Visual C++ Redistributables, click on the 2005 x86 version, and uninstall.  (Don't touch any other versions.)  Then download and install a new copy from Microsoft:

Restart after it installs.

If that doesn't help, try playing in a clean boot:

When you restart, go through the Task Manager's background processes list and shut down anything that doesn't need to be running.  Some programs will still be active in a clean boot; I don't know whether all the Dell/Alienware support apps would be, but if so, they're definitely on the list of "doesn't need to be running."  You can guess a bit too: if you accidentally kill a critical process and it doesn't restart itself, just reboot your computer.
