Newer DirectX-versions use to be compatible with games meant for older versions, games - in turn- which have been programmed for the newest DX-version exclusively, won't run on an older DX. If you'd install DirectX 9 on Vista (I can't imagine that this would be possible without getting problems anyways) you'd take away some core parts Vista needs to display the desktop and parts of the new effects. See if you can find a compatibility mode, something like this is in VISTA, as MS did not dare to create a fully exclusive 64-Bit environment, which would require all new software.
EDIT: Also, some hardware manufacturers still have problems with their driver versions for VISTA. You might want to check if there are driver updates for your mainboard's chipset/HD controllers and/or video card drivers. Switching back to certified driver versions (WDM) may help too. Some games tend to crash because adware/spyware found their way to the puter, occupying memory or cpu. Getting tools like adaware or PestPatrol could help too.
