I will attempt to answer my own question. This is from a forum at Tom's Hardware:
This mechanism can be disabled (for debugging purposes) by adding a REG_DWORD named TdrLevel to the registry at: HKLM\System\CurrentControlSet\Control\GraphicsDrivers and assigning it a value of '0'. Doing this will simply stop the TDR from resetting your display driver (this may simply tell your computer to allow itself to freeze instead, read on).
Another thing you can try (for debugging purposes) is adding a REG_DWORD named TdrDelay instead of the TdrLevel entry. This entry specifies the number of seconds that the TDR will wait before resetting the GPU/Driver. The default value is 2 seconds, so you can up to to 4 or 10 seconds to see if your system regains responsiveness. Don't leave it at the default value of '0' that's put in when you create the key.
Keep in mind that in most cases these registry entries will not be there and you will have to create them. NEVER mess with the registry if you don't know what you are doing.
To remove the keys (after debugging), simply use the Find function and match it to TdrLevel or TdrDelay and delete the entry.
