Vista - Standby Mode Disabled

hello everyone,
Installed an Update for 'ATI Technologies Inc- ATI PCI
Express(3GIO) filter driver' few days back.........and since then my Standby
Mode has been disabled!

When seen in Device Manager my Display Adapter 'Mobile Intel(R) 945 Express
Chipset' has resource conflits (Cannot find enough free resources that it can
use, you will need to disable one of the other devices on this system). And
this was not the case before installing update!

Also the In 'System Devices' 'ATI PCI Express (3GIO) Filter Driver' has
device conflicts (IO and MEM range have been used) by other device).

So in nutshell it seems the prob has been caused by the 'Driver Update'.
When i tried uninstalling the driver.........the next time i booted
windows.......it again installed almost all my Ssytem devices......like
ATA,Display etc etc........so thnk its not a good idea to uninstall the
driver?

Even in 'Uninstall Update' i dont see this particular update present!

Any Solution highly appreciated.
