S.T.A.L.K.E.R Run problems

[Xavion88]

I just got this game installed on my P.C. It installed fine, except for when it told me my video card didn't stack up, which is BS because it's a Asus Nvidia 6800 512mb. Anyway, i finished installing it and I tried to pllayi it only to be told "The ordinal 11 coud not be found in the dsound.dll" All of the .exe file icons didnt have the piscture that comes with rge game, instead the icon was the little white picec of bpaper with the winows thingy on it. Does any one know what the proble m could be?

I would sure like to play my game. Any help is appreciated, thank,.s
