Display Driver Unstable when playing

[Chico008]

Hi

I experience some problems when playing Alien Swarm.

I have a NVidia 9800Gtx graphic card, with the last driver (258,96)
and when i play, the game go back to windows, i have a box saying de display driver did not respond, and is beeing relaunch.
then i go back to the game again, but it does that several times in a sigle game.

How can i fix that ?

My PC:
Windows 7 Ulti 64 bit
Nvidia 9800Gtx 512Mo
Intel I7 i860

Thanks for your help.

Sorry to disappoint you guys. but this is Source Engine...

Just check L4D forums, there are TONS of similar threads :P

Do you have a link or 2 to the topics ?
seems they have made some clean up in the L4D forums.
Or copy the solution here, so people who are in the same way would find the solution easier.

There was NO solution, sorry.
Well, except default drives: reinstall all drivers, remove some software, reinstall OS...
