Re: Game Freezes on start up
@JanelleHD As a test, please try playing in a clean user folder. Move the entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop, and when you launch the game, a clean folder will spawn with no content. (Your saves and other content will be intact in the folder you moved but temporarily not read by the game.) Don't add anything to the new folder yet; just let me know whether you can get far enough to start a new save and play in live mode for a bit.
As a test, please also restart your computer, wait five minutes without opening any apps, open only the Task Manager, and let me know how much memory is in use (the number in the Memory header) overall. Then flip to the Startup tab, take a screenshot of the startup apps, and post it here.
I'm wondering if something on your laptop is eating most of the RAM because your dxdiag shows a large page file that's almost all in use. The page file is where the processor stores data that would normally be held in memory but can't fit, and while something around 5-8 GB in use is pretty typical, yours was at 20 at the time you ran the dxdiag. It's even more surprising given your laptop has 16 GB RAM installed. Point is, it's worth seeing if this is a problem both in general and potentially for Sims 4.
