3x 1080ti troubleshooting

Hey, I tried installing a 3rd 1080ti in my rig and since booting up my pc with the 3rd card it has been giving me this error from Nicehash (http://bit.ly/2ssoat4). The card is recognized in device manager but gives error "Windows has stopped this device because it has reported problems. (Code 43)" http://bit.ly/2tqdybb . When trying to install drivers through Geforce experience, it would start the install and then uninstall all of Geforce experience to get the current drivers running I had to download them separately from the Nvidia website. The cards are running on a brand new 1200w platinum corsair PSU. Any help is greatly appreciated.
