Graphics Cards Not Getting Power?

My computer crashed last night as though it lost power, I smelled a bit of burning, and the power supply felt very warm. I took the PS out this morning, and brought it to a store. They tested it and confirmed it was fried. Bought a new one, and brought it home. Computer starts up again now, but I get no display. I checked, and the fan isn't even running on my card. This is an old card (GTX 570) and I was using a single cable with 2 8 pin (6+2, using only the 6-pins) that came with the new power supply. I tried plugging it into multiple outlets on the power supply (modular, so there's a VGA1 & VGA2). I also tried seating the card in 2 different slots. My motherboard has an onboard graphics card, so I plugged my monitor into that instead and it worked fine.

I figured maybe when the PS went it fried my graphics card too. Talked to a guy at the store, he said it would be that for sure ("no need to test it"). I bought a new graphics card - GTX 1060 3GB mini. The fan on it also won't start spinning. It's using a different cable (1 8pin 6+2 cable, just the 6 plugged in), and I have tried seating it in different slots too. I'm at a loss...even if the motherboard's fried in a way that only affects PCI-E slots (if that's possible), shouldn't the power run the fan on the graphics cards? As a last ditch option, I tried updating drivers, but "NVIDIA Installer cannot continue; This graphics driver could not find compatible graphics hardware." Any ideas on next steps?
 
Solution
It's certainly possible - in all my years, I've never personally seen a graphics card do that to a motherboard, but there's a first time for everything.

Thanks scuzzy. Is it plausible that multiple PCI-E slots died (I've tried two of the three), yet everything else seems to be working?

So, adding to the mystery:
I bought a new motherboard. Popped in my old graphics card (GTX 570), and the card wouldn't start (again, everything else works fine). Popped in the new graphics card (GTX 1060), still no luck. Reseated the GTX 1060 in a different PCI-E slot - and it starts! Pop the GTX 570 into the slot that was just working...and it still doesn't start. Put the GTX 1060 back into that slot, and it also won't start now.

Is it possible that the GTX 570 is the source of the problem, and is somehow breaking PCI-E slots when inserted (or perhaps at attempted startup)?
