Computer Randomly Freezing

[insanima]

Just built this computer and am encountering an extremely frustrating problem. Under a decent load, sometimes even a light load, the computer will stop and freeze. I'm not sure if it is a temperature issue or a mobo issue or a cpu usage issue. What i believe (not that it matters bc i suck at computers) is that the mobo is forcing the computer to stop when the cpu usage hits 100%. Just a theory. I dont think cooling is an issue because it is liquid cooled and, upon monitoring in the process of a freeze, the temps are relatively ok. Any help would be appreciated.

Specs:
asus maximus vi micro atx
i7-4790k
Nvidia Titan Black
4TB HDD
250 GB SSD
16GB (2x8 GB) corsair vengeance RAM
Windows 8.1
Corsair H100i (i applied artic silver thermal paste)
NZXT h440
i have dual monitors running (2560x1440 and 1920x1080)
