Weird Colorful stripes appear in Sims 4!
Please Help!? These strange colourful strips keep appearing in my game!?
Okay so the good news is your drivers are indeed sorely out of date. Your graphic card is ancient so you won't be able to play with a very high quality of graphics but if you update your drivers you should see a notable improvement. Download the drivers from there:

Install, reboot and try launching the game again. Tell us if it helps! 🙂
