Question SLI trouble after upgrading to Windows 10 ?

[ZSchoonover]

Hello all,

I recently took the plunge and updated my PC from Windows 7 64 bit to Windows 10 Pro. Up until that upgrade, my graphics cards had been working fine. I didn't have any issues the first few days after the update, however, last night (about a week after the update), Windows started disabling my second graphics card and is providing the following message in device manager "Windows has stopped this device because it has reported problems (Code 43)". I updated my drivers for both cards and was able to get it up and running again last night, however, this morning I am finding it is disabled once again. I've done the following, but nothing has worked:

1. Checked to ensure BIOS is updated to the latest version (it is).
2. Updated the drivers on my graphics cards.
3. Checked to ensure Windows is up to date (it is).
4. Uninstalled, cleaned, and and reinstalled both graphics cards.

Any assistance would be greatly appreciated. My builds specs are:

Graphics: (2 way SLI) Nvidia GTX 770 Classified (Drive on both cards: 27.21.14.6647)
MOBO: Sabertooth 990FX (BIOS version 1604)
RAM: 16G
CPU: AMD FX-8120 (3.89GHZ)
OS: Windows 10 Pro 64 bit (Version: 20H2; Build: 19042.985)

Check the firmware level of each card, one may be using an older firmware.

The firmware on the graphics card is the same. Just pulled both graphics card and booted with one installed at a time to verify. The firmware version is 80.4.c3.0.72 on both cards. I've been able to get them to SLI every now and again, but it is not consistent at all.

SLi support in games has been declining rapidly in recent years. it may just be the case that some of your games are supporting it and others aren't, which is why you're only able to get the second card to work sometimes.

I would be inclined to think the same thing, however, it is a matter of Microsoft disabling the card, not the game. I've been checking the Nvidia Control panel on startup, before starting any games, and many times the SLI options aren't even available. I then go ahead and check the device manager, which will show the second graphics card is disabled. After restarting the computer multiple times or trying to reinstall the graphics card drivers, I usually can get it to work again.
