I have an Optiplex 760 with Dell's ATI Radeon HD3470 256MB, running Windows 7 Professional x64 (I also experienced this problem with the 32-bit version).
Dell's latest drivers for the card work fine (version 8.640), but anytime I try to install a newer (including the latest) version of the ATI drivers, Windows bluescreens. The initial setup procedures go ok, and I can choose to install, then I select Custom (although I have tried Express with similar results), and when it begins to detect the hardware, it gets to about 10-20% and then bluescreens. The same thing happens when trying to install the Avivo Video Converter; it bluescreens on the detection page. So far, I have only tried the driver-only package and the Avivo converter.
As far as I can tell, Dell does not have a custom BIOS on their video board, and ATI reference drivers have always worked on past boards.
Dell's driver package does not seem to include any specializations, so I cannot see why the ATI drivers would fail.
The Dell drivers are here: Drivers and Downloads
Here is the error from the crash report in the System log:
Log Name: System
Date: 11/13/2009 1:15:10 PM
Event ID: 6008
Task Category: None
The previous system shutdown at 1:13:06 PM on 11/13/2009 was unexpected.

Usually I can work around things like this, but I have not found any solutions so far. Using the Dell driver would not be the end of the world, but I would prefer to run the latest, and I certainly want to run the Avivo converter.
Thank you in advance for any help or advice!
