DirectX – Games

Hello,My problem is when I install a game on my pc (in this case Rome Total War & Company of Heroes) i install the game successfully with the DirectX and when i try to play this message comes up on my screen: “Rome total war failed to find DirectX 9 which is required for the game to run.Please Reinstall Direct X.”
I already did reinstall DirectX from the game and I even downloaded it but still nothing.
By the Way….these games were playing fine before I formatted my pc.
So i quess some settings changed because of the format
Thanks
