directshow causes dxdiag to crash and i can't use direct x with games i get the blue screen of death with nv4disp.dll. I have the latest drivers... Why does directshow crash and what can i do to fix it? reinstall directx? This all makes sense now because streaming media has been horrible. I don't need to tell you specs i just want to resolve the directshow issue. direct 3d also doesnt work... thx
