Hi!

I have Lenovo IdeaPad Y500 with two Nvidia GeForce GT650M -graphics card, and supports Sli. Sli worked well until I updated my OS from Windows 8 to 8.1. Now Nvidia Control Panel doesn't detect the another graphics card, so I can't use Sli either. Please help me!

I already have updated the latest Nvidia driver and Nvidia Control Panel. Nothing works.

I have tried to install BIOS-update from Lenovo, but I don't know how to install it. I have read this threat from Lenovo Forum, but I don't understand the latest post at last page, which is the solution. Could somebody tell it by step-by-step?

Thank you! You can also contact me via Steam, my Steam name is Finagleiris.
 
I had a similar problem with my pc and the windows 8.1 update, for now I'd stay with windows 8 until the issue with the update and sli is resolved.
