tiffani16 I see a pile of new errors that point to the graphics driver, but the driver shouldn't be a problem after you've used DDU to remove it and reinstalled it. So this could be a hardware failure, directly or not. Before jumping to the conclusion that the GPU itself is failing, please make sure that it's not overheating while you play.
GPU-Z will track temperatures for you and is lightweight; you can leave it open while Sims 4 is running and check back whenever you want to see the current and max temperatures. Anything below 80º C is fine in that it's not dangerous; the hotspot can get somewhat hotter than that.
If you do see higher temperatures, open the case and make sure the fans are spinning. A broken fan is easy to fix and doesn't mean anything is wrong with the GPU overall.
Please also make sure that the supplemental power cables are connected properly, in fact it would be best to unplug them, blow out both sides with compressed air, and reseat the connectors. Your GPU needs one 6-pin and one 8-pin cable, and best practice is to use two separate cables if your PSU supports it, rather than using two connectors originating from the same cable.
The suggested PSU for this graphics card is 450W, although given the age of this system, I'd hope for more like 550W to be on the safe side. But the more important detail is what power supply you have: make, model, specs. A higher-end unit with a lower wattage is likely to perform better, in the long run, than a higher-wattage unit from a less reputable manufacturer.
