Whenever I go in-game and I minimize it, sometimes it says display driver has stopped working and has recovered and the game freezes. Then I have to exit out of Tb. How can I fix this?

Either get a newer/better driver or toggle the graphics reloading option in TB.
(it's in the advanced options)

Really you shouldn't minimize games though, it upsets Windows & drivers. TBH games don't like losing focus full stop, so it's all about making the crash happen less rather than curing it.
