I turned my PC on this morning and I got a black screen with 9c down in the bottom right corner for a minute, then the code A2 appeared in the same place an it just stays on it. Any ideas on how to fix this problem? 

My system specs:

CPU: Core i7 5820k

CPU Cooler: Corsair H100i v2

RAM: 32 GB DDR4 

Motherboard: MSI x99 Gaming Pro Carbon

GPU: GTX 750ti

PSU: Corsair RM850i

A2 POST code usually means IDE detet, This usually means one of your drives is causing the issue (HDD, SSD, or Optical). Unplug them one by one and see what happens when you try to boot
