No longer able to Enable SLI with NVIDIA Control Panel
I recently switched to a new case and after re installing everything into the new case and turning on the computer I found I was no long able to enable SLI on NVIDIA control panel.
Things I have tried:
1. Reinstalling drivers
2. swapping card slots
3. test cards in another system
4. changing SLI bridge
5. checked for windows and NVIDIA updates
6. Made sure cards are fully seated
7. updated motherboard BIOS
8. Made sure the system detects both cards

Setup:
i5 4670K
EVGA 760 4GB x2
750w PSU
MSI Z87- G45 Motherboard
Windows 7 Home Premium
16 GB Vengeance RAM
120 GB SSD 1TB HDD (If it matters)
Any suggestions would be great as I am out of ideas on how to solve this problem. All three of my monitors show up and display but they are not detected as one panel and instead as 3 separate monitors. Also I have been looking all over for a solution to the same problem but nothing has worked.

Try these two solutions:

Under the NVIDIA Control Panel, for the tab labelled "Configure SLI, Surround, Physx", there should be a check box titled "Maximize 3D Performance." Check that, it will enable SLI.

If that doesn't work:

In the BIOS, typically under Advanced, manually chance the speeds of the two PCI Slots to the same settings.(On my Sabertooth 990FX, I had to set them both to PEG/PCI to get my 770's to SLI.) The process for this will vary from board to board.


Sadly neither of these things worked because the first one I couldn't find what you were talking about and the second just flat out didn't work.


When you tested the cards in the other system, did both cards come up with the SLI option?


Yes I tested them with my buddies computer and the SLI option came up.


If it works in another computer, it cant be an issue with the cards. Its gotta be a motherboard or conflicting driver issue. There are some tools out there like the Guru3D Driver Sweeper, to clean out drivers that you want to completely clear out. You can check that out over at ->> http://www.guru3d.com/content-page/guru3d-driver-sweepe...

If completely clearing out the display drivers doesnt work, its gotta be a motherboard issue, and you've already flashed the latest BIOS for it, so its gotta be a defect/broken part somewhere, I would think.
