BSOD - atikmdag.sys with AMD 6630M graphics accelerator

About 5 days ago, started to received a BSOD on a Dell Vostro laptop with the 6630M accelerator.  Was able to recover by disabling the AMD accelerator in the control panel devices. 

Standard windows updates were installed - however, nothing that references this area of the operating system was included in the most recent windows updates.

 

Running the system now with the AMD accelerator disabled.  Have attempted to repair by updating the latest dell driver and the latest AMD drivers.  No joy.

 

Any help will be appreciated.
