Any ideas? I'm going slightly mad here. Motherboard is Gigabyte GA-Z97P-D3. I've searched all over the internets and can't find a working answer.

PSU: Seasonic S12 II Bronze 620W
CPU: Intel i5 4590. Has a Zalman cooler.
RAM: 2 x 8GB Corsair DDR3 1333Mhz
Other components aren't connected anymore, but include NVIDIA GeForce GTX 760 GPU, 2 SSDs and a regular HD.

- Turn on
- Turn off after a few seconds
- Turn itself on again with all fans whirring and reach the POST screen
- Switch to a black screen with a mouse cursor and flashing key cursor
- Reset back to 1

- Replacing the motherboard battery
- Removing the memory sticks, causing the motherboard to continuously beep when turned on (a good sign for motherboard health, at least)
- Removing all SATA connections and PCI-E cards and using only motherboard HDMI out
