cannot find nvlddmkm.sys/SLI problem

so my first problem is my sli bridge is not detected, i tried putting the fingers on both sides, diagonally even, flipping it around, no dice, this was an sli bridge i took out of the packaging today but i wouldn't be surprised if it was bad since i don't know how long it's been in that packaging.

i'm trying to use differentsliauto to run my 2x 970's together (different brands, sli bridge not detected) and i can't find nvlddmkm.sys in c:\windows\system32\drivers.
