  1. Roll back to the earlier version of your drivers and wait for a new release....
  2. I'm having exactly the same problem. This happened last time I updated the drivers and I rolled back, but don't want to have to keep on doing this.

    Have hunted everywhere online for help with this and it's driving me crazy. Have disabled/enabled the cards, taken them out and reseated them, deleted all previous Nvidia drivers, but still my SLI is not recognised. It's obviously nothing wrong with the SLI setup itself because it was working perfectly before the driver update, so if anybody could provide any advice I'd be hugely grateful.
  3. Is your system even seeing the second GPU? You can check it in the device manager under display adaptors. If it only shows one GPU then you will have to go into bios and see if you can enable it.

    If that doesn't work then try this. Take out the second card boot your system up then shut is down and then put the second card in make sure everything is hooked up right and reboot.

    If that doesn't work pop out your CMOS battery for ten min, and pop it back in and reboot. If none of that worked. Do a restore point before the update. Then go from there. Good luck.
