are we talking about the stock standard NVIDIA GeForce GTX 1050 Ti model?
you say you checked drivers but what you decribe sounds very Gpu issue... test to see other software run fine, something that uses the Gpu like a game or video rendor is what we need to know
+ if you put the old drive back in the game is happy again?
anyway if other games and rendors i.e, the system gpu works then i'd assume the issue is that the game [or more likely Steam] is not detecting hardware correct... when you reloaded the game did you actually reinstall them or just copy \verify old files across?
