SLI FIXES 

It seems that there is soemething in windows stopping some of the Nvidia drivers from properly uninstalling . It seems that dome files from previuos drivers are actually left behind causing conflicts . Follow the below steps to fix this .

1 . Download driver sweeper from GURU3d website .    Go to the download page . Once downloaded install it .

2 . Download the latest Nvidia drivers .

3 . Uninsstall your graphics drivers .

4 . Run driver sweeper .

5 install your new drivers .

FIX 2

Another update on the SLI issue . Some have reported that using the latest beta drivers works for them . It may not work for everyone but would be worth a try for those having sli problems .

FIX 3

I have read a lot of new finds on the sli side of things . It seems that the sli setup itself is not the problem . Its actually to do with the voltages on both cards . It seems that there is bios update differences on some cards . Check the voltages on both cards using MSI afterburner and set them accordingly . It seems that dx 11 takes offence to this and causes the game to become unstable and eventually freeze up .

The problem is Sli works in all other games, it worked even in BF3 before i installed this.

Why isnt the SLI working ? i can only play with one video card.
