Random Crashes

[NE0XY]

Hi,

 

Sometimes when I'm either gaming, watching movies surfing or just writing in word or something, in other words: it doesn't matter what I'm doing my screens (dual monitor setup) will go black and saying "no signal" but there will still come sound from my speakers, but keyboard or mouse can't change anything, like the volume or something. Sometimes it stays like this for a long time until it just shuts off or sometimes it will reboot itself after a short time.

 

What could be the error?

I'm running Windows 8.1 

CPU: i7-4930K @4.5GHz.

GPU: GeForce GTX 780Ti

RAM: 32GB Dominator platinum DDR3

PSU: EVGA SuperNova P2 1200W

MOBO: Asus Rampage IV Black Edition

SSD: Samsung 840 EVO 120GB

HDD1: WD Black 2TB

HDD2: Seagate something 2TB

 

Thank you

Back off the oc on GPU and CPU a tad. The silicon might be getting older and therefor not capable of supporting the overclock

It's all relatively very new, CPU maybe 5 months and GPU just about 1 year. It's also water-cooled so they're never really warm.
