All the hardware problems i read here seemed a little different than me so I decided to create a topic.
My configuration :
Windows 7 64 bits
Nvidia GTX460
4Go DDR
i5 2500k
My problem :
When I launch the game, if i launch a new game or choose "continue", i see the loading screen. When the loading is finished, I stay on this screen, wich seems freezed, but I hear the sound of the games. If I do Tab or Echap, If i press the mouse buttons, I hear the the sounds of the menu or of the attacks. So the game is not really freezed, just the video.
Sometimes after I quit the game I have a message from Windows telling me the video driver stopped to answer.
It seems I haven't got the problem on "low profile" but I can't say wich parameter make the video freeze this way. I managed to play 2 times this morning and after that I could play without any problems (some framerate falls but it's another problem).
I updated my video driver, my audio driver, tried the compatibility trick and the audio trick. None of this works !
Help me please.
