System Specs:
Motherboard: Asus Rampage IV Formula Edition Socket 2011 Motherboard
CPU: Intel Core i7-3930K 3.20GHz Hex Core Processor
RAM: Corsair Dominator GT 12GB DDR3 Memory Kit
GPU: Sparkle Geforce 560Ti (1024Mb iirc)
OS: Windows 7
PSU: Can't remember the make/model, I believe it has 750/850 Watts

This issue can occur at nearly any time, I'm uploading an image of the error which I took with my phone.

I tried to fix the issue by replacing the old motherboard (nForce 780i and Intel Core 2 Quad with new cooler) but nothing changed unfortunately.

So it leaves me looking at the HDD's or the PSU in this case, I know it's not an overheating issue as I was looking at Youtube when the last one occurred and other times I've been running less stressful applications.

Every thing is new except the graphics card, PSU and drives.

I have kept an eye on all temperatures across the system and nothing jumps out at me, I am seriously at my wits end with this one, new PSU or replace the drives? (Or both? :/)
