@LeoSalinas73 The first and simplest test is to remove your entire Sims 3 game folder from Documents\Electronic Arts; you can just put it on your desktop. Launch the game, which will create a clean game folder with no content. Start a new save, and test Create a Sim, Build/Buy modes, and live play to see whether you get a crash.
Please also check your in-game frame rates. Your graphics card is powerful enough to generate very high fps, and Sims 3's built in fps limiter doesn't work. High frame rates alone can sometimes cause crashing, even when everything else works as it should. To see your fps, open the cheats console (crtl-shift-C) and enter "fps on" without quotes. A number will appear in the upper right corner of your screen, and it should never go above 60, which is the refresh rate of your monitor. If it's much higher, let me know, and I can post instructions for manually limiting it.
If Sims 3 still crashes in the clean game folder, and your fps isn't the problem, then the next step is to reinstall a Microsoft Visual C++ redistributable, specifically the 2005 x86 version. You can uninstall the one you have and download a new copy from Microsoft. Click the Windows icon in the lower left corner of your screen, select Settings > Apps, scroll to where the file is listed (be sure to get the 2005 x86 version), and uninstall. Then download a new copy from here:
https://www.microsoft.com/en-us/download/details.aspx?id=26347
(This download includes all versions of the 2005 VC++, but you only need to run vcredist_x86.exe.)
Let me know if none of this helps, and we can move onto more complicated steps.
@LeoSalinas73 If your framerates are going too high, then you should address that before anything else. The first tool to use for an Nvidia card is the built-in Control Panel: right-click on the desktop to open it. Here's a screenshot of the settings you want to change, under the spoiler:

Since you have an Origin install, be sure to use TS3.exe, not TS3W.exe, to set up the profile for the game.
Control Panel only works when you play in fullscreen mode. If you like to use windowed mode, or if CP doesn't keep your fps down, the next app to try is Nvidia Inspector (free download). You'll need to explicitly cap fps at 60; you can also try 59 or 61 if 60 doesn't work. There's a screenshot for Inspector in the link above, under the second spoiler.
And please keep testing in a clean game folder, with nothing else added to it. That makes it easier to eliminate other potential sources of the crashes.
@LeoSalinas73 It sounds like the problem was your fps then. Strong cards like yours can easily overwork when running TS3, and that alone could cause all the crashing you describe.
If you have more problems, feel free to post back, but the fps limiter might be all you needed to fix the issue.
