The sims 4 is laggy on a brand new PC

@Ssimina  There are several obvious issues with your system.  The first is that while this computer is new to you, its graphics card is older and quite weak for Sims 4.  (The whole system is older, but the processor, memory, and storage should be fine.)  While it shouldn't require laptop mode to work, it's not even anywhere the level of the Nvidia GTX 650 recommended for the base game.

You can and should update its driver though; at least one of the errors in your dxdiag is probably related to the driver.

There are a few crashes of Windows processes, so it's a good idea to run a couple of basic checks of your Windows system files.  Here's how:

• Hit Windows key-X
• Choose either “PowerShell (Administrator)” or “Command prompt (Administrator),” whichever option is offered
• Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes into the window, 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 “Command prompt (Administrator)”
• Inside the window, copy and paste “sfc /scannow” without quotes into the window, and enter
• Post the message you receive here

Origin is also crashing, listing a component of the 2013 VC++ runtime (used by both Origin and Sims 4) as the faulting module.  So it's best to uninstall and reinstall both 2013 runtimes and reinstall them.

Hit Windows key-i, choose Apps, and scroll through the list to the Microsift Visual C++ 2013 Redistributables.  Click on both the x86 and x64 versions, and uninstall.  (Don't touch the versions from other years.). You can download new copies directly from Microsoft:

Be sure to install both the x86 and x64 versions, although you don't need the _arm version, which is for a different class of device.

It's a good idea to uninstall Origin "the hard way" and reinstall too, in case Origin is the issue and not the above runtimes.  Clear its cache first, since a couple of files aren't covered by the hard uninstall.

After doing all this, or however many steps you want to start with, restart your computer, and see how the game runs.
