Solved CPU over voltage error/PSU surges detected

Specs: Windows 10
CPU: Intel® Core™i7 Six Core Processor i7-5930K (3.5GHz) 15MB Cache
Cooling: Corsair H60 Hydro Series High Performance CPU Cooler
MB: ASUS® X99-S: ATX, HSW-E CPU, USB 3.0, SATA 6 GB/s
GPU: 4GB NVIDIA GEFORCE GTX 970 - 1 DVI, 1 mHDMI, 3 mDP
PSU: CORSAIR 650W CS SERIES™ MODULAR 80 PLUS® GOLD, ULTRA QUIET
RAM: 16GB KINGSTON HYPER-X FURY DDR4 2400MHz (2 x 8GB)

First turned on computer to find this;

When I pressed F1 to go into Bios, see if it needed resetting my PC shut down,
turned it back on and this happened;

Monitor is off.
Fans are running.

Motherboard:

Power and Reset is on.
Red numbers say: 00
'CPU LED' is a constant red light.
No beeps.

Inside case;

I'm stuck, don't know what to do, any help appreciated. this happened after I took the battery out of the motherboard, to reset BIOS as the computer wasn't responding to the "on" button on the case, this seemed to fix it but after the internal clock wasn't remembering its settings and now this has happened.

btw I tested everything earlier this year with no problems, other than needing to
replace RAM, as it was causing blue screen and shut downs.

IF you had a cheap power supply I would have said replace it immediately BUT you have a quality power supply. While this does not rule out that it is having a problem, it does point out that there might be other problems including but not limited to the power coming into the power supply. With unstable power I would not risk a BIOS update at this point. If you are not using one I would recommend getting a UPS (Battery back up) and not one of the cheapest they sell. Look for something round this one or the same quality:

Unlike a surge protector, a UPS can 'fill in' voltage drops as well as cutting off voltage peaks/spikes and that can be important to the life of your components.
You can also have the power in your home or at least that outlet tested if you have other problems or this continues. The rare and extreme possibility is that the power company transformer on a nearby pole is beginning to have problems but at this point just make sure that any expensive electronics have a surge protector they are plugged into.
Other possibilities include a bad power supply and motherboard since both have power regulating circuits that may be bad. One clue is to look into BIOS set up for the primary voltages (12V, 5V, & 3.3V) to make sure that they are within 5% +/- from their nominal values, if any are outside of these ranges then you may need to return it for replacement under warranty (I think you have 5 years on the gold series but I have not looked).

You have to be a little bit crazy to keep you from going insane.

You have a quality name brand PSU but I see it's modular. Check all the cable connections on both ends. Each additional plug is another potential failure point.

Enter the BIOS & correct all the settings that changed due to the reset, save & exit.
