Recently I upgraded my computer from Vista Home to Windows 7 pro. Now all of my games worked with windows vista, all sudden after upgrade only few works now such as NFS: undercover, Cities XL 2011. but not others like Guild wars, Fallout New vegas, they keep crashing whenever I open them.

So, I decided to update my drivers. my current drivers are 8.17.12.5896 & updated to latest 260.99. after the update all my applications started crashing mainly showing nvd3dum.dll is the cause. & it disabled my Direct3D acceleration.

Just to be sure I ran Memtest & it passed.



any suggestion is welcome :)  :cry:  :cry: 


edit:
Also, I'm running dual monitors on this computer.

I'm seeing whenever I'm trying to install 260 driver I get BSOD with BAD_POOL_HEADER, makes no sense, GFX card is fine & memory is fine.


confused as hell.

a 9400gt is very very low standard gpu,very low,but if you use 800x600,1024x768,with medium settings in less demanding games,it can surprise you
