My sims 3/4 games aren't working!

I might have fixed the issue, but I will try it and let you know the outcome

It won't even get to a load screen. Just says "Failed to start"

simkat40​  Sims 3 has always required DirectX9 in order to run.  That didn't change with the switch from Origin to the EA App, and there was no need to install or reinstall DX9 or any runtime when starting to use the EA App.

If you need help with getting Sims 3 to work, please describe your issue.

You might need DirectX now just to run it since EA killed Origin. I miss Origin  because I never had issues to start my games. I hope this helps or maybe check out videos to see what needs tweaking in your game. I have to fix mine again too ever since EA added Sims & Sims 2

@Dasiapasiaa  Restart your computer and try running DISM and sfc again.  It looks like you also figured out that the first command was missing the spaces.

Did what you told me to and it had an error ☹️

@Dasiapasiaa  Even though it technically meets the minimum requirements EA lists for Sims 3, your laptop is far under the practical requirements, especially with more than the earliest few expansions installed (anything past Late Night).  That doesn't mean you can't play at all, but I wouldn't expect performance to be great, and you might not be able to play with Pets or Seasons, or even Island Paradise or Into the Future, at least not without significant issues.  The laptop is also under the minimum reqs for Sims 4.  You can of course try to play both games; I just don't want to make it sound like the issues you're seeing are entirely fixable.

One thing that will help is playing either game with nothing else running in the background, not even a browser window.  Putting the EA App in offline mode can help too since it eats more resources while online.  RAM is in particularly short supply since you only have 4 GB installed.

Your dxdiag lists a number of generic Windows errors, so I'd suggest running a couple of basic checks of your Windows system files:

• Hit Windows key-X
• Choose either “PowerShell (Administrator)” or “Windows Terminal (Administrator),” whichever option is offered
• Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes, and enter
• The system will start validating soon. If it throws an error, please list it here
• After it reaches 100%, hit Windows key-X again
• Again, choose “PowerShell (Administrator)” or “Windows Terminal (Administrator)”
• Inside the window, copy and paste “sfc /scannow” without quotes, and enter
• Post the message you receive here

Restart your computer, hit Windows key-i, select Update & Security, and click the box to check for updates.  If any install, restart again afterwards.

For Sims 3 itself, all NRaas mods would be fine to use with the exception of StoryProgression.  The other mods are neutral or help performance, but SP increases the game's RAM use, and significantly on higher settings.  If you really want to use it, run it on Snail.

For your other mods, try the 50/50 method to figure out what was preventing the game from working:

If you're still looking for your missing saves, download Everything, from VoidTools, which is a free and highly efficient search tool.  Search for .sims3 , which is the extension for any Sims 3 save, and let me know what you find.

Game works perfectly fine without the mods, loads up slower but- I can still play without it freezing. 

Here's the file for the DxDiag: 

@Dasiapasiaa  For Sims 3, please test a new save in Sunset Valley with no mods or custom content, just to set a baseline for performance.  If you don't want to manually uninstall everything, you can simply rename the Sims 3 folder in Documents > Electronic Arts.  This contains all your user data (saves, saved households and builds, etc.), and renaming the folder will prevent the game from reading it.  So you can test with none of that content, then restore the original name later when you're ready.

Please also run a dxdiag and attach it to a post.

Hey! My sims 3 game is kinda working I got some mods and stuff its definitely lagging and takes about 6 minutes to stop freezing (Yes I kept timing it lol.) Onedrive is on my computer but I never touch it because I dont wanna mess anything up on there. 

I did uninstall sims 4 but I will try the cleaner and let ya know how it goes. 

I don't know if this is any help but I do own an Asus Laptop and its supported by windows 11!
