Motherboard's PCIe slots went kaput? Need your opinion.
I have an ASRock 970M mini-Atx motherboard, AMD FX-8350, single NVidia GTX 970 card. The other day, I soft-reset my computer, and the graphics just stopped working. I tried the card in the other PCIe slot, nothing. The monitor works - I tried it on another computer. I tried the DVI and HDMI - neither work with my computer anymore, but they do on another. I took a known good card, and nothing. The card works in its own PC. The only thing that gives me pause is that I am unable to test this card in another PC at my house - the card is too long, and none of the other power supplies have an 8-slot PCIe power connector.
I'm thinking the motherboard's PCIe slots just went kaput. Does this sound right?
Additional details: My GTX 970 has a white LED. It comes on, like always, when I power the PC on. As does the fan - and the fans on the known good GPU that I substituted (which does not require an additional PCIe 6 or 8 pin power connector). So I know that power is getting to the PCIe slots.

Could also be the PSU. If the cards aren't getting the proper voltage, you'll have no display. Do you have any other PCIe devices to test the slots with?
I do not. I built this computer almost a year ago. It has an EVGA 750+ Bronze, so the PSU is not underpowered.
