Okay, so it was working perfectly fine yesterday with no issues. Then I move my PC downstairs and all of a sudden the PC doesn't wanna detect the 2nd GTX 970. I have the SLI Bridge connected still and everything. Left everything as it was before I moved it downstairs.

I tried reseating it. (Didn't work)
I tried swapping it with my other 970. (It worked, but the other 970 didn't work in the 2nd slot)
I tried uninstalling the drivers from my PC and reinstalling. (Didn't work)

I checked to make sure everything was plugged in and everything still is. I don't know how many times I checked the Device Manager to see if it was there and it never shows up. The fans and everything are moving on the gpu as they should.

Please don't tell me it's a bad slot because it was working fine yesterday. I know it's possible, but there's no way.

Do you have the second card installed in the PCIe x16 #2 slot or is it in the #3 slot? Have you TRIED the #3 slot just to see if both cards are recognized at the same time? Have you double checked to see that the PSU end of the cables going to the supplemental power connectors on the graphics cards, have not come loose at the PSU?

What is the model of your CPU cooler? If you have a heavy cooler, then sometimes moving your tower can cause the cooler to shift, which can cause the CPU to flex and break the connections from some of the pins on one side of the CPU cooler while pressing down more on the other side. Since there are PCI and memory operations that run through the CPU, this can sometimes affect both graphics and memory operations, even causing them to be non-functional.

Normally, I'd say this is most likely to be a PSU problem, but that HX1050 is a very good unit and I'd be surprised if it simply failed during the move. If it was a cheaper unit, then I wouldn't be surprised as we see this happen quite often when systems are moved to a new location or new hardware is added.

On that unit, eh, not as likely. More likely for damage to the board PCI traces to have happened if you moved it with the cards installed. Did you leave the CPU cooler and graphics card installed when you moved it?

And yes, there "is a way", whether you want to believe it or not. Every piece of hardware that ever existed worked fine right up to the point where it didn't.

I have it in the #2 slot. I would try the #3 slot, but the way my mother board is and how I have some cables/wires connected, those block me from putting the gpu in that slot.

I've checked the PSU end and everything is fine.
