Left4Dead Can`t run in Window 7 Ultimate 64Bit?

[CloudKee]

I hope I can get help in here!
I don`t have any idea how to solve it,
I just update my OS to Window 7 Ultimate 64Bit OEM,
After I install all driver, everything working fine,
I try to test my gaming performance,
Warcraft III is running perfect,

When I try to run left4dead, the window pop-up,
"left4dead has stopped working"
I had no idea how could I fix it!
Any one had this problem?
Help me please

Have you tried to run L4D in Compatibility Mode for Windows Vista: http://www.sevenforums.com/tutorials/316-compatibility-mode.html

Also...have you updated the game to the latest version?

I am running L4D on Window 7 Ultimate 64Bit without problem. I did get it to run better by disabling the "use multiple cores" option in the L4D Video Options Control panel.
(of Note: you might have to run L4D AND Steam using the "run as Administrator" option) :sarc:

yeah, steam has some problems i can't run bioshock but everything else runs fine including L4D, stupid steam

More likely a driver issue i think. I have both L4D and Bioshock on my PC and they run fine. Both run using Steam.
