Second GPU isn't being detected by NVIDIA Control Panel

[Gooobee]

Hello! I had just installed new drivers for the GTX 1080s and "Device Manager" detects both graphic cards, but one displays a yellow sign. When I open up "NVIDA Control Panel" it only detects one graphic card, also there isn't an option for SLI. Yes, I have opened up my case and re-seated the second graphic card and re-installed the SLI bridge.

P.S: I have also uninstalled NVIDIA drivers and re-installed them with a clean installation.

Have you tested both cards individually to make sure that one isn't faulty? They can both be detected but the yellow sign could mean it's not working properly.

try using the latest DDU linked below 17.0.3.1. Boot up in safe mode, run the program the reinstall drivers with clean install that should fix things up for you. be sure to make a back-up before running.

I've only backed up my pc once with an external hard drive, I don't have one at the moment, any other ways to back up a PC? I'm not much of an expert in this haha.

do you have a hdd or partition separate from your OS drive? if so put all you important files there. otherwise I would take my chances and just run ddu in safe mode. I use it all the time and it has yet to crash my computer, i was just giving you the just in case things go wrong advice and you need to reinstall/repair windows...unlikely but always possible when updating you registry which DDU does. Regardless it has fixed this exact issue your having for me more times then i can count.

Also making a restore point may be helpful in preventing/fixing potential crashes.

If I go into safemode and use DDU, I won't have to back up my pc?

also to get in safe mode go to start menu, (if win 10) right click and choose run, type msconfig and choose selective start-up with networking then reboot and run DDU.

you should back-up important files if you can, its always the safe bet when installing/unistalling software or modifying the registry. It's just a good habit but if you do not have an external HDD or internal HDD (or even separate partion) not assigned to the OS you won't have any other options then hope for the best. Again personally never lost any files using DDU but I always try to give the "safe" advice when posting on tom's.

It's still not detecting the other graphics card on NVIDIA Control Panel and still displaying the yellow sign in Device Manager.. I've tried twice.

You may have to re-install windows. if that does not work you may have fried your second PCIe slot and need a new mobo.

I'm going to open up the case an do something, then run DDU again, i'll update you after!

sounds good!!

Yay! it worked, I just took out the second graphics card again and just re-seated it, applied the SLI bridge again, boot safe mode, ran DDU, then installed the drivers and it worked! Thanks so much man!
