The easy one first: the Origin Web Helper Service errors can be fixed by shutting down the service entirely. In Origin, hover over your username and select Application Settings. Under Application (the first header), scroll down to Start-up options and disable the service. Then hit Windows key-R and enter "services.msc" without quotes. Scroll through the list to Origin Web Helper Service, double-click, select "Disabled" under Startup type, and click Apply to make the change stick. Then restart your computer.
Among the TS3 crashes is one MSVCR80.dll error. This is a part of the 2005 VC++ runtime (x86 version). It's simple enough to uninstall it and download a new copy from Microsoft. Click the Windows icon in the lower left corner of your screen, select Settings > Apps, find "Microsoft 2005 Visual C++ redistributable" on the list, and click it to uninstall. Be sure to uninstall only the x86 2005 version. You can download a new one directly from Microsoft; again, you only need to install the x86 version:

To see memory use while you're playing, bring up the Task Manager. You can hit crtl-alt-delete and choose it fromt the options, or right-click the taskbar at the bottom of your screen. Once it's open, you can alt-tab between it and the game. Be sure to select More Details if you haven't already; this will let you see the memory use of all currently open apps. If you see RAM use in percentages, right-click on the column header to switch to absolute values. Let me know how much memory TS3 uses as soon as you've loaded a save, then keep an eye on it until the game crashes. At the very least, this should be eliminated as a cause of the crashing.
