Im trying to get rid of the nv4_disp error and ive been told to reinstall the drivers. I have a XFX geforce 6800 XT and a AMD 64 3200 i just need to know exactly what drivers i should install. Thanks

Go to the Nvidia website HERE. (http://www.nvidia.com/content/drivers/drivers.asp) Download, and install the latest drivers.

See if that solves your problem.
