Driver and Windows Kernel. I enable get screen blank and sli works but as soon as I disable it get instant blank screen and BSOD. Can't figure it out. I have 2 gtx 580's worked fine. As soon as I added titans got this problem of not getting out of sli without a BSOD error. I am thinking forst trying sli bridge and next re-installing wondows thinking registry is corrupt pertaining to nvidia drivers.
