Cannot boot into Windows, PC stuck on a looping on/off cycle.

Hey guys,
I recently ran into some problems with my system, whereby after doing a fresh reinstall of Windows 10 after my upgrade from Windows 8.1. At first, after the reinstall, things were going fine. After a week without use, my PC wouldn't turn on because it got stuck in a looping cycle of on/off, before I could even see the BIOS prompt or Windows loading screen. I cant even load into the BIOS now. I tried unplugging my HDD leaving only my SSD Boot Drive in, but to no avail. So I guess its a BIOS problem? I can hear the PSU cycling on and off with the clicking sound seconds apart, where my chassis and CPU fans spinning for a few seconds before going off again, monitor turning on and off again, in an endless cycle. I could only turn it off by cutting the mains power.
My specs are:
i7-4770K (un-overclocked)
Asus ROG Maximus VI Formula
Corsair Vengeance Pro 16GB (2x8GB) 1866mhz
Noctua NH-D14
Asus GTX 780 DCII OC
Samsung 840 Pro 256GB
WD Caviar Black 2TB
Corsair AX1200i
If it is a BIOS problem, what should I do? Must I replace my motherboard since it wouldn't even boot into the BIOS? Or is it a PSU problem?
Appreciate the help guys, thank you.

  1. BIOS problems are usually only caused by failed update attempt.
    It looks like one of components failed, but to early to tell which one. Unplug all drives, graphic card, usb devices, leave just one stick of ram and try booting. If it works, start adding components one by one. If it does not, check what code is displayed on motherboard (upper right corner).

  2. Don't forget to clear the CMOS first, then try those steps. You can use the jumper or removing the CMOS battery.

    Sure thing, I will do that when I'm free. Thanks!
