Do Nvidia cards still have problems reading .mov files?
I had an Nvidea gforce something or other i think at my job and every time I went to play a .mov it would crash.
I googled it and they basically said you're fucked lmao. Was a little while ago so I assume it has been fixed but who knows. It was nuts, they were telling ppl to go complain to apple lmao. Got sick of it eventually and got a radeon hd card.

It should have been addressed by now but maybe try playing some mov files after the install.
You don't need to uninstall the drivers if you don't want to but no reason to keep it there.
Device manager ftw.
Best of luck with it.
