PCI-E Slot Problem

    Okay, a year and a half ago, I built a gaming PC. The motherboard is an Asus P8Z68 Deluxe (PCI-E 2.0) version. I put in the top two x16 PCI-E slots, two Geforce GTX 560 Ti's in SLI, and they worked grand.
    I went into my Nvidia Control Panel a short while ago and noticed that it was seeing only the one graphics card, where before it was able to see both perfectly. Same with Windows 7's Device Manager, it only listed the one GPU. Both cards were receiving power (I could tell because the fans on both cards were spinning). My power supply is an OCZ ZX 1250W Gold (overkill I know), so it wasn't a lack of juice. It's the second PCI-E x16 slot that's the problem, nothing in there is picked up by Windows. I tried swapping both cards, Windows was only able to see the card in the top slot (confirmed both cards work by testing having just the one card in, in the top slot). Just now, I put in a Creative sound card I had lying around, the X-Fi logo on the side lights up, but as far as Windows is concerned, I haven't done anything. I've also given the case a thorough cleaning with compressed air cans, no luck.
    Is the slot dead do you think? Why is it that there's power going to the card but Windows can't see anything? I'd be able to write off the slot as dead if there wasn't any power going to the cards, but there is.

    It mightn't be completely dead, just damaged or slightly fried. Given that the sound card wasn't working right, it does sound like a dead slot. You could try a few other things, like uninstalling and reinstalling the drivers, just in case. Have a look in the device manager to see if anything shows up. Update the BIOS. Maybe even a Windows install (to a different disc as a trial so you don't lose all of your information). It does sound quite like a dead slot though.
