Stuck on loading screens, infinite saves, ect

not sure why files didn't upload

LadyDarkSorrow​  Some of the errors in your dxdiag are crashes of the graphics driver, and some are what we see on certain high-end Intel processors that the motherboard may overclock by default.  The graphics driver crashes can also be caused by an unstable overclock of the CPU or GPU, so if you've manually overclocked either one, please revert to stock settings.

If that's not the issue, look for a BIOS update for your motherboard.  I can't see from your dxdiag which board you have, but when you find the model number, look up the Asus support page for it.  Your current version is 1658.

If that doesn't help either, or you already have the newest BIOS, you can try disabling CPU Turbo Boost, which Asus sometimes calls something slightly different.  It'll be in the BIOS under Advanced settings.

If that doesn't help either, do a clean uninstall and reinstall of the driver, as described here:

You're right that the newest Nvidia drivers have their issues; you can find older drivers here:

https://www.nvidia.com/en-us/geforce/drivers/

If you'd like to see what kind of crashes you're getting going forward, check the Reliability Monitor.  Click Windows key-R and enter "perfmon /rel" without quotes, and you'll see a chart of errors and updates with a column for each day.  Today is on the right.

Look for an error that happened at exactly the time of your most recent Sims 4 crash.  If you find one, double-click it to see more details.  If you don't see a new error, check back in an hour or so—the Reliability Monitor doesn't always update right away.  Feel free to post what you find.

For reference, the LiveKernelEvent 141 errors in your dxdiag are a timeout of the video driver, and the Sims 4 crashes with faulting module python37_x64.dll are the overclocked CPU errors.

puzzlezaddict​  I read your post and updated bios from 1658 to 1820. and no i got this pre-built from new egg "never touch the bios" I don't do over clocks. Overclocks Kills PC.. and that was scary and sim atm started up. so far as for Nvidia driver i'm firm on that stance.. now little confused about CPU Turbo Boost . looks like I have 2 of them

Intel CPU Turbo Boost Technology 3.0 and Asus ver CPU Turbo Boost mode not sure witch one 

LadyDarkSorrow​  I would disable the second one first; I think the first one is fine in most cases.

I wasn't saying you had to update the Nvidia driver, only that this particular install of this driver is apparently not working as it should.  It could simply be corrupt, in which case reinstalling the same version should clear up the issue.

puzzlezaddict​  you been awesome, really you have been awesome with your help.. thank you.. I updated the bios like I said and found the this update was for raptor lake cpu from throttling or something like that, my pc slowed down, it's not hyper like it was.. sims been really stable not getting any LastCrash or LastException. txt. i've been loading, saving, jumping to lots random stuff exiting and loading game been good so far..  also I just found cpu turbo from watching video on the asus prime z790-p wifi I went ahead and did that cpu turbo off and pc went to a crawl so not sure to leave it off or turn it back on again? it's now really slowed down.. will do Nvidia reinstall again with ddu thing .. sign..hate Nvidia. Im up tonight nothing better to do

LadyDarkSorrow​  You can reenable the CPU turbo setting if you want; as long as your system is stable after the BIOS update, you don't need to do anything else.

You can also hold off on DDUing the graphics driver until and unless you get another LiveKernelEvent 141 error in the Reliability Monitor.  While these point directly to the driver, they can be caused by an unstable overclock of the CPU, because an unstable overclock of the CPU can cause almost any error.

puzzlezaddict​  played a few hours with turbo off and been playing with turbo on and this game has been stable. no crash at LiveKernelEvent in Reliability Monitor. nothing in the Sims folder like LastCrash.txt , another word "it does what it's told"  the only thing i got was a 2 last exception 1 was for Sim leaving lot while waving and holding something and the other was for screenshot.. either way, game been running great.. now I've been testing mods like Mccc and ui cheats extension.. so think we solved it, well you solved it!! thank you!

Okay so I spent last night figuring out the problem, taking each mod out and figuring out which didn't let me save, I pretty much only have CC now, and a more slot traits mod, more traits and ww. I can save just fine, loading works, HOWEVER now the problem is when I try to play and join a household it kick me back to the world selection menu, I've tried with an household I haven't created and same thing, any tips ?

Same issue here

Yeah nevermind the infinite loading screen is back, I give upp
