Sims 4 crashing badly DURING CAS

Hi Crin, sorry for the very delayed reply! On the day that I posted here I had spent a couple hours trying to solve my Sims crashing, during which I had to force shut down my laptop about four times. Unfortunately, I think this crash actually broke my computer - just a day later, my pc would not turn on or charge (I have never had issues with my pc and it's only a year old). I have only just received my laptop back after having to have the motherboard replaced. As all my data is gone, I can't post the DxDiag or any files. I'm in the process of downloading all my Sims games again - I'll let you know if I still experience the same crash. I worry that if I do I will have to stop playing Sims as I don't want to risk having another motherboard die. ☹️ 

Thanks for taking the time to reply!
