Hi !

I'm using Dell inspiron 15R N5110 core i3 with Nvidia geforce gt 525m 1gb dedicated graphics card. I wanted to install nvidia graphics driver version 296.10;Release Date: 2012.03.13; but it showed failed; cause:-

Nvidia update version 1.7.11 status-not installed
PhysX system software version 9.12.0213 status-not installed
HD Audio Driver version 1.3.12.0 status-not installed
Graphics Driver version 296.10 status-not installed
3D Vision Driver version 296.10 status-not installed

What should I do? where can I find these??

Please help! Thanks in advance...
