"Windows - Display driver stopped responding
The nv4_disp display driver has stopped working normally."

For the past few days, I've been getting this message every time I play any total war game. It usually takes several turns though, but when it happens, I have to restart the entire computer.

I have no idea what it means, please help me.

Uninstall the previous drivers and the install the new ones.
All the TW games are very sensitive to drivers. Maybe this driver cause problem to the game. If this happens install a previous driver who you know is O.K.
