@VildaCullen Outdated or not, I still play TS3 and enjoy it very much, as do many others who are active on various sims forums.
When you listed your specs, you didn't include your graphics card. The ideapad 320 has a number of potential configurations, so it would be helpful to see a dxdiag and confirm exactly what hardware you have. You can run one and attach it here using the "browse" button.

But based on your other specs, I think you may only have an Intel 620, which is an integrated card, and not a particularly powerful one at that. The most demanding EPs—Pets, Seasons, then IP and ITF—really do require a strong dedicated card to run properly. Your card is probably already overstressed trying to render your home lot, and Map View may be pushing it over the edge. I understand that this is a new problem, but it's entirely possible that you've already damaged your card by trying to run TS3. It's also possible that choosing higher graphics options increased the load on your card to more than it can handle.
It's also entirely possible that the crashes are due to your computer running out of memory. You also only have 4 GB RAM installed, which isn't enough to run more than the base game and a couple of packs. (The minimum to play with all or most packs is 6 GB, with 8 recommended.) Windows will take up some of your 4 GB for itself (my Windows 10 takes about 1.5 GB on startup), leaving less for TS3 than it needs. Pets and Seasons require a lot of memory to run, and the small spike in RAM use from entering Map View may push your system over the limit.
This is less critical, but it should also be noted that your processor is U-series, for ultra-low power, meaning it's designed to throttle power, perhaps below what TS3 needs to run properly.
I'm really sorry to say this, but I don't think you should be playing TS3 on this computer. It's just not built to run a moderately demanding game like TS3. The base game and a couple of early packs on low graphics settings might be fine, but trying to run Pets or Seasons, and maybe even Supernatural or University, is probably more than it could handle. Even putting the crashing issues aside, continuing to play could do serious damage to your hardware.
