The System Specs
Intel Pentium 805D @ stock
ECS P4M800-M Pro (VIA® P4M800Pro chipset)
2x1GB PC3200 Corsair XMS
MSI 6600GT (using ForceWare 97.46's for Vista x86)

The Problem
My motherboard has onboard video. I have done my best to disable it through the BIOS (giving AGP precedence and preventing it from getting assigned an IRQ) and it would seem like everything is working fine. I'm using the AGP 6600GT w/ DVI out on a single display.

I came off a Windows XP install (which was working fine) and decided to try out Vista. I did a clean install on a new hard-drive and it looked like everything worked fine. All the drivers were installed via Vista's installation, I didn't have to manually install anything.

There is no noticable lag, but anytime UAC pops up with a warning or I press Ctrl+Alt+Del, my screen turns black and my mouse freezes for about a second, then it shows the prompt. (Please note it is not "dimming" like it should be, my screen will go completely black, then come back to a "dimmed" screen, I'll hit an option, it will go back to a black screen, then back to the regular screen)

My Progress
Someone recommended turning off hardware acceleration. I came to find out that "Your current display driver does not allow changes to be made to hardware acceleration settings. Additionally, SiSoft Sandra was reporting that I had no general capabilities

I thought, maybe it's the latest ForceWares? I was only able to find a modified nightly ForceWare driver though another forum, so I decided, why the hell not? I went to manually update the driver when Windows finds two graphics adapters.

If I double click on "Standard VGA Graphics Adapter," I have no problems. (other than the max resolution is 1280x1024 and is fuzzy, but there is no lag when doing CTRL+ALT+DEL and I can adjust Hardware Acceleration.

If I double click on the top "NVIDIA GeForce 6600 GT (Microsoft Corporation - WDDM)," all the problems resume but I can get 1680x1050 resolution but there is that black screen lag + no hardware acceleration.

The lower "NVIDIA GeForce 6600 GT" does the same thing as the (Microsoft Corporation) one.

I think I've narrowed it down to the graphics drivers, there is obviously some conflict. Any help is greatly appreciated!

Besides disabling it in BIOS, have you gone into the Device Hardware Manager and turned it off?

Windows likes to find new HW and install Drivers (and even enable it) all by itself. You might need to turn it off (disable) in the Device Manager.

They don't both show up together in Device Manager.

When I install the 6600 driver, it shows: http://www.verityhw.com/uploader/files/1/6600.JPG
When I install the Standard VGA Adapter driver, it shows: http://www.verityhw.com/uploader/files/1/standard.JPG

Hmm, I thought it might be under Sound, video and game controllers or possiblely System devices.
