6990M and BSODs (Possible Solution!)

So, I just got my upgrade R3 with the 6990M the other day and I decided to install AMD reference drivers (Catalyst 11.7) over the newer Dell graphics drivers... Well... BSOD! Then I decided to reinstall the Catalyst 11.7 drivers again without uninstalling everything... Restart computer... BSOD! Never made it into Windows. Then I decided to just hit F8 during boot and chose "Last Known Good Configuration". That worked great. Windows booted again and I had a working Catalyst 11.7 installation. Sweet.

I then decided I wanted to see if the OLDER Dell graphics drivers for the 6970M would work... So I uninstalled everything including the drivers directly from Device Manager (both AMD and Intel graphics drivers) till I was presented with the standard VGA adapter (low res). I then restarted the computer because the Catalyst Install Manager (Dell 6970M) would not recognize the graphics card. I then proceeded to install the OLD Dell 6970M drivers. NO BSOD! Then after that I installed the reference 11.7 drivers on top of the Dell drivers. NO BSOD! I then tested that switching graphics still worked. YES!

Anyone wants to give this a try and confirm that it works (besides me)??

 

*Bump* Anyone tried the above (using Dell's OLD 6970M drivers on a 6990M system, so installing reference drivers doesn't result in a BSOD)??
