Windows 7: D3DX9 error messages when launching games.

I have a d3dx9 error widely encountered and I dont know why I didnt do anything it just started.I cant play my games on steam and I payd for them and not only steam games any DX game.What shoud I do?

Try updating to the latest direct x,update graphic drivers and update windows to the latest service pack and updates through windows updates if you haven't.
Latest direct x release link Download: DirectX Redist (June 2010) - Microsoft Download Center - Download Details

Well i have another problem when i try to install direct X says an error occured crash pleafe reffer to DXlog

Try checking windows for internal errors go to your start bar and type cmd then press enter,make sure you're in your admin account. In cmd type sfc /scannow. Let windows scan your computer for errors and when it is done and if it finds errors then restart your computer. Then try installing direct x again.

Well.... i cant search either because it show only files music and other stuff like that

Try holding the windows key at the same time pressing the R key.Then type cmd and that should bring the window up and do what i said in my other post.

Ok got that but what about steam games? they dont show wich d3dx they require

Direct X is automatically downloaded when the Steam game is downloaded and installed so there's no issue there.

Steam's DX download policy... Valve engineer explains why Steam keeps installing D3DX files with each game download | VG247. Point? You'll always get DX, whether you want it or not

No the problem is that when i click play it says that latest directx is required to play the game.
