7970's stopped working

post #1 of 3
Thread Starter 
After installing a second 7970, my PC would boot, but nothing displays. When booting up with my integrated graphics, neither card appears in device manager or 3rd party software. I have tried updating my mobo bios, changing around power connectors, and unplugging replugging.

Also the cards are under a custom watercooling loop but both work in my other pc.

My specs are i7 4790k, maximus vii gene, 8gbs of gskill sniper ram, and Evga G2 750watt

Thanks

Fans spinning?

Yes and no since my card are both in my watercooling loop. But the computer powers up all the way with both card plugged into the mobo and with power jut no display from the cards.
