Crashes with Hard Drives and Wifi Card

[richcamp]

Z77x-up5 th
I3770k
Sandisk SSD
4x 2tb (software mirrored)
Apple wifi card via pci e adaptor

The computer ran perfect with hard drives and all but now with the wifi card it crashes. If I unplug the hard drives its more stable and if I unplug the wifi adaptor. But it just gets the spinning ball non stop. Any suggestions? Thank you
