CPU and GPU temps stay around 30C to 40C when idling. CMOS has been reset numerous times. All the cables are securely in place. It's undergone a fresh installation of Windows 10 not so long ago. I've opted to get a new graphics card because integrated graphics would refuse to work after I sold my 660 to a friend. Every time start my computer, it would immediately shut down and start up again in a loop. Even when the graphics card is removed.

However, my main issue computer shuts down at the most unexpected times. It's almost impossible to use demanding applications and even a simple web browse. Could anyone please help me?

Specs:
Intel Core i7 4770K
Asus STRIX GTX 970
Asrock Z87 Pro 3
G.SKILL Sniper Series 8GB (2 x 4GB) DDR3 1866
Corsair CX600 Power Supply
Corsair H110
Seagate 1TB HDD ST1000DM003
Intel Dual Band Wireless-AC 7260
Corsair Carbide 500R
Samsung Super‑WriteMaster SH‑224DB

EDIT: Also I should mention that none of the hardware was overclocked.

Have you tried running a stress test such as Prime95? Maybe the processor is unstable.

Also, well the CX Corsair PSU series isn't very good as of what I've heard, I may be wrong. I'm thinking that could be a factor. Say there's a voltage drop on the 12V rail that lasts like half a second or something, maybe that's what makes the computer turn off? I'm just thinking out loud. If you can first start by trying another PSU. Good EVGA ones aren't terribly expensive on Amazon.

In my case (Overclocking my fx 8320 that lost the silicon lottery with a average cooler), cpu temp was the issue, is the cooler installed correctly?

What makes you say that? Also, I'm not sure if getting another motherboard would be a viable option for me until it is clear that it needs to be replaced.

I don't think it's a heat related issue. My CPU temps stay around 30-40C when running idle. I'm fairly confident that the H110 was installed correctly. But I can certainly check my stock cooler if it is necessary.
