I've already got the board replaced with a higher revision. I got a week to use it, but it did not happen until yesterday and the screen went blank and it does not allow me to shut down.
The worse part is, the issue is very clean. I didn't notice any abnormal power fluctuations before 'it' happened and happens when the system is under load. It does not damage the processor or any other parts of the system.
What do you think could be the culprit of the Motherboard failing? Video card (Galax GTX 970 Exoc Black)? water cooler (Corsair H80i unlikely), or the HDD drives? (Unlikely), or probably the LED lights?
RAMs, have you checked? Try running Memtest86+ for atleast 3 to 6 hrs, or wPrime with 1024M. You can use Prime95 to test not only your RAMs but also your CPU.
