Mac Pro shuts down during boot up
I installed the inateck PCI express card to get USB 3 into my mid-2010 Mac Pro. That seemed to go smoothly. But when I went to boot up, the power came up for about 5 seconds, then the computer turned itself off.
I removed the new card, but got the same result after.
Does anyone know what might be going on? Did I fry the motherboard by using my bare hands to install the card maybe?
