Essentially mate you want to download this;http://downloads.guru3d.com/NVIDIA-Inspector-1.94-download-2612.html
When you run it, next to the driver version (about half-way up on the right hand side) is a small button - click on that and it will load all the game profiles within your driver set. In the top left, click in the drop down box and type 'Dead Island' - it will load all the preferences for that game. Directly underneath where you just typed is a green bar, and in white text it should say 'deadisland.exe' in white text. To the right of the drop down box are a series of buttons (off the top of my head I can't remember exactly what it looks like) there should be a button which allows you to add an .exe to the current profile (I think it has a small green cross on it). Click that, browse to your game directory and select 'deadislandgame.exe'. Make sure it appears next to 'deadisland.exe' in the green bar. If it does, click 'Apply' in the top right, close it all down and give it a try.
This isn't guaranteed to work - but it enabled SLi for me on my 590 and now my GPU usage is about 40% higher than it was before. I'm not experiencing any crashes either (I'm on driver set 280.19).
