Vista 64 Aero problem w/ 3 monitors and 2 video cards...

So I just got my new Gateway 30" XHD3000 to go in the middle of my dual 20" Dell 2001FP's and everything is just gorgeous and wonderful, save for one little problem.


I am running Vista Ultimate 64 with a Q6600, 4Gig RAM and an 8800GT for the Gateway and 1 Dell and a 7900GT for the other Dell. Also, I'm using the 169.09 Nvidia driver (for both vid cards).

The monitors are set up like this:

#3(Dell in portrait on 7900GT)---#1 (Gateway on 8800GT port 1)---#2 (Dell in portrait on 8800GT port 2).

Now, before I got the Gateway tonight, I was running Aero w/o problem on both Dell's. But now that I throw a 3rd monitor in the mix on a 2nd video card, monitor in the #3 spot goes haywire. It's getting a signal from the computer, but it's diagonal and completely scrambled.

I have tried "updating my score" (which is 5.7), I have tried both DVI ports on the 7900GT, I have tried switching which monitor is hooked up to 7900GT. Nothing has fixed the problem and I'm beyond frustrated now. The 7900GT works fantastically running everything BUT the Aero Theme. Grrrrrrrrr.

Also, native res is 1600x1200 and I tried 1280x800, 1280x768, and 1280x720. All have the same problem.

I should also add that tried using my new Gateway 30" on the 7900GT "slave" video card and the same problem happened.

Again, this is ONLY w/ Aero. All other themes/appearance settings work w/o problem.

I have even uninstalled/cleaned/reinstalled the 169.09 drivers.


If anyone has encountered the same problem and/or knows of a fix of this, PLEASE let me know.

TIA.

Also, Whenever the/a screensaver pops up, the same "diagonal scramble" pops up and it remains there, even after the other 2 monitors 'wake up' for about 30 seconds, then it pops up and clears itself and is then useable again. I took a screenshot to try and show what I was talking about, but in the screenshot, the monitor appears just fine.

20+ views and noone has any thoughts? Please fellas?
