Code 43 error sli

[thatSamaritan]

I just recently purchased a second MSI GTX 760 for sli purposes, but upon setting up the card, windows displays a code 43 error in the Device manager on the second card.. Both cards work fine individually so i cant seem to see what the problem is. I have uninstalled then re installed the drivers and also ran a windows update but to no avail. The sli option also refuses to come up in the Nvidia control panel.. I am running short on options and am close to just selling both the cards for a 970 or something but just want to make sure I haven't missed anything.. 

Any suggestions will be much appreciated! 

 

p.s about a year ago i had an asus 760 and that worked fine in sli with the msi, so its really strange..

 

My system: cpu- amd fx 8350 

motherboard - asus sabertooth 990fx r2.0

psu - corsair 750w 80+ bronze 

OS - windows 7 64 - bit ( win 8.1 on an ssd in the system, same problem there)

ok so the drives have installed and still the problem persists.. maybe its a software conflict somewhere

I have the same problem, same motherboard, but my cards are GTX 670s. I've tried everything, the last thing I can find to do is upgrade to Win8 because this is a Win7 problem (not verified, read this on Tom's Hardware).
