I was having some bad graphics bug where after every reboot I would have to reinstall the drivers, but then I found a program called "Driver Cleaner Pro" and used that to fix my issue.
so now my graphics run ok but now I do not have the SLI option on my Nvidia Control Panel where it usually is. It only shows the Physx options now.
I have attempted to reinstall the latest driver (Nvidia 258.96) and even installed the previous driver (Nvidia 191.07) but neither have seemed to bring back my SLI.
I tried various searches have checked the device manager and the cards are recognized. I also ran GPU-z and they were discovered too. I also checked both cards that they were producing images when plugged into a monitor.
The only thing I can think of at the moment is maybe I have a bad SLI Bridge? Would I need to replace that to get it noticed again? Help would be most appreciative.
If you've completely formatted and reinstalled, there must be a hardware problem someplace.
However, you said you updated your mobo bios. I'm assuming you mean you Flashed it to the newest BIOS version? If so, doing such sets all the BIOS settings to "Default". You might want to make sure something in the BIOS was changed. Some boards you can enable/disable SLI ability.
