Random Crashing

Hi, the last few days my Sims 4 game keeps crashing at random times. It started on the 13th where it crashed at 16:23, 16:57 and 17:09, on the 14th there were crashes at 11:47, 12:26, 13:15, 13:43 and 14:14 and today I've had crashes at 9:44, 9:54, 9:59, 10:23, 10:28 and 11:25. As you can see it's not letting me play for long. I had no problems with it before the 13th, I've tried without mods and still experience crashing. I've also tried repairing the game which hasn't helped. The game will load in fine but after playing for a short time it will just switch off. I bought 3 expansion packs on 12th but had no problems playing with them installed that day.

Please help me sort this out, I've only recently started playing the Sims 4.

I've attached a DxDiag.
