So today I installed my 2nd video card, at first it worked fine, both cards were working. I was tinkering with overclocking my cpu, when I noticed my card in slot 2 wasn't showing up anymore. I got worried so I swapped slots and the card that wasn't picking up was fine but not the other one isn't picking up. I checked that it's getting power, fans running on both. But the 2nd card isn't detecting !! I have uninstalled the driver and reinstalled it twice trying to clear this issue to no avail. Any suggestions would be greatly appreciated, this is so frustrating lol knew I should have just went for 1 card.

yes, also did that cause I overclocked too far with too low a voltage and system wouldn't boot, so I had to do a cmos reset. Z87-gd65 MB, well it won't allow me to put it in SLI since it only recognizes the card in slot 1. It's only happening with that card and at first it was running fine. makes no sense to me really, unless my slot is messed up. but that would seem odd. And I do have the newest bios installed, I haven't reinstalled it since this happned tho, that might be my next course of action.

just went into device manager and noticed there are two things not recognized but it says they are Logitech, which doesn't make much sense cause the only two things I have Logitech are my mouse and kb but yet when I unplug them the two things stay in my device manager. wondering if it could be picking the card up wrong... I'm so confused and tired lol
