Doozy Posted April 5, 2017 Share Posted April 5, 2017 Hey there, rancorx2. I'm not sure how much help I can be, but maybe my suggestion can help narrow down the problem. When I upgraded my Y500 to Windows 10 with a clean install, I vaguely remember having some issues with SLI, initially.. Perhaps, try the following: Download the latest Nvidia drivers from their website, then uninstall all Nvidia drivers and software, completely, from your laptop. Reboot, reinstall everything, and reboot again. Optionally, you could disable the Windows update service temporarily, at the beginning of this process, to prevent it from attempting to reinstall a driver automatically. I'm not totally sure, but I feel like my issues in the past had something to do with Windows update and the way it handled this. Or, perhaps, letting Windows install the driver for you, first, then updating it, might work. Another option: Choosing to "clean install" in Nvidia installer vs not choosing the clean install. This may or may not make a difference, but I've heard it might in some cases. You might have to attempt this multiple times, from what I gather from other, similar cases on other forums. If a third or fourth attempt with variations (like disabling wupdate) doesn't fix it, then this is probably not the issue. Lastly, I found a slightly old guide along the same lines as the steps I listed, above, that you may prefer to check out, here: https://www.reddit.com/r/nvidia/comments/3fdcqw/upgrading_to_windows_10_read_me_first/ Good luck, I hope this helps in some way!
