Have the drivers been updated?

 

If they haven't, update them and return to the thread to give the results of the updates.

If they have, what exactly are the games you're wanting to play?

It's a software problem. Try reinstalling Direct X. Uninstall it completely, then use CCleaner to clean out the Registry, then reinstall.
