SLI Problem - Havent found a solution in the forums?!?

[mangoose]

I just posted this directly in the nVidia thread, but thought this would open more possibilities...

I have been having some trouble with my new SLI system, and have looked around and not found anything like this problem...

Ill start off with my system:
Case: Antec Nine-Hundred
CPU: Intel Core i5 Lynnfield 2.66 Ghz Quad
Motherboard: MSI P55-GD80 LGA 1156
RAM: 8GB Corsair XMS3 DDR3 1600 (PC3 12800) (4 x 2GB sticks)
Power Supply: Corsair CMPSU-850TX 850W (SLI Ready)
Graphics Card: 2 x XFX 9800 GTX Black Edition PVT98FYDBU 512MB 256-Bit GDDR3
OS: Windows 7 Ultimate - 64bit

then some opticals, hard drives, and some speakers...

I am running two cards in SLI, and when I am browsing around windows, opening folders, surfing the web, and watching movies in WMP, everything is fine. However, as soon as I open an application (and I am not sure of the correlation between these, other than they all are *outside* of the regular "windows" interface), i get some strange blue flashing lights almost like every frame displayed has a second blue-tinted shadow on it...here are the programs so far that I have seen this in:

3d Mark 06
3d Mark Vantage
Warcraft 3
Borderlands
Crysis
Call of Duty 4
Dirt

If anyone has any idea on what is causing this, I would love to hear it, and before you ask, yes, I have connected the SLI bridge, installed proper drivers, and everything else...also these cards are IDENTICAL, so there shouldnt be any issue...right?

Have you tried using only one card without SLI to see whether one or the other is the cause of the problem?

when i switch back to regular (ie NON-SLI), the problem goes away, but thats the same as not even having the second card...

I havent swapped them yet, and tried using only the second card in the primary slot, will try when i get home.
