Sims2 4gb patch and crashing

Hi Guys! I've been playing the sims 2 for a while. I have a pc now finally and I'm working off of Windows 10. I wasn't able to get Ultimate Collection through origin, but got it online. That one is basically all of the packs, and no combined stuff and expansions like the original UC. I tried to do the 4gb patch. it didn't work. I downloaded it because I am having sudden crashing with my pc. Last time it cause a BSOD. Does anyone know how I can expand my memory, or am I doing it wrong? I don't see an exe file unfortunately. but the icon I click on to start the game is the Mansion and garden icon. I can't find anyone else who has this same issue. any idea?
