Hello!

For the past few days I have been building my new gaming computer, after finishing I booted up the computer, installed windows, and began using my computer. later I was looking in the bios to see some random stuff and I came across the PCIe slot section and found that it said nothing was there even though I have 2 980TIs installed in SLI. So I downloaded CPUID to see if I would have the same problem and on the graphics page it was only showing the integrated Graphics on my CPU. So I went on the internet to see if I could find the answer but came up with nothing. So I went into the BIOS to try to get the cards to show, but with no luck. So now I'm here open to any suggestions.

PARTS
CPU- Skylake I5 6600k
GPU(s)- 2 MSI 980ti
RAM- 32gb DDR4
MB- Asus Z170
(If you need anymore parts Just ask)

I'm sorry for my studidness...
the reason my cards were not showing up is because they were not fully powered, once I plugged in my last two VGA power cords they worked.
