Sims 3 Help

Hello! I recently got a gaming laptop and although I prefer to play sims 4 nowadays I miss playing with horses in sims 3. I was told in another thread that I would have to do something to play sims 3 in order to not harm my computer as it doesn’t cap something (I’m not sure what.... not really computer smart here) and I reinstalled it, but again I don’t want to harm my computer. I don’t really play for more than a few hours if not even more than one hour a day and sometimes I skip a day here and there. Can someone help me? It’s a newer laptop and it runs sims 4 great but sims 3 it also said it couldn’t identify my graphics card. Thanks to anyone who can help!
