7100 build, can't get games to work
I have the next setup:
Asus Xonar D2
6 Gb of O>C Gold edition
P6T deluxe V2
Sapphire ATI 4870 X2
My problem is that I can't get certain games to work. Flatout works fine, so does GRID, The Witcher, Nation red, Bioshock and assassin creed.
Arma 2 and HoN(Heores of Newerth) Won't Work. When I try to execute one of them, my Windows 7 gives an error saying "C:\windows\system32\d3dx9_40.dll is either not designed to run on Windows or it contais an errorr. etc"
This is clearly DX problem as far as I can go to it. Would any of you know what to do? I've uninstalled DX, I've reinstalled all the games, I've reinstalled GPU drivers and so on.
