nVidia SLI Problems

[P1nnacle]

Recently my SLI just stopped working, and I haven't been able to figure out what the problem is. I have 2 GTX 570s on a MSI Z87 MPOWER motherboard. I've tried completely removing the drivers and reinstalling them, replacing the bridge, and updating the bios. Both of the cards work and show up in Nvcpl, but there is no SLI option available,

Like I said, I have already reinstalled the drivers. All of my motherboard's drivers are installed and up to date.

CMOS was effectively cleared when I updated my BIOS. I have also used the second BIOS. It did not affect the problem.

Yes, the SLI tab/option does not show up in Nvcpl. Physx takes its place.

The error was having a PCIE 1x card in the third PCI-E slot, this conflicted with the two cards working properly.

The problem is solved, I just can't select the answer that has the solution, because I wrote it.
