Slow game, can’t save lots

Ever since the last update my game takes FOREVER to load. I took my mods out, restarted, repaired everything and my game still takes forever to load up like it’s in the dial up era. 
I also have an issue where I try to save my lot into my library or onto the gallery it will not do either. The library issue I’ve had for a while but not the gallery. 
My computer has taken a total turn and works for the worse. This all started when I downloaded the last update…
