Computer stuck in reboot loop

[SKREEBUS]

As title says, I have been working on trying to resolve this issue for months now. I started having issues last summer with this issue and now It won't even let me get to bios before it restarts. I have replaced the CPU, RAM, Mobo, PSU, and GPU trying to fix this issue. So most of the parts are new. Keep in mind this issue started with the old components, and is still continuing. And the old GPU is now in my wifes computer and works just fine. I got the computer to get to bios once and was able to get it to instant flash to the newest bios, but still keeps rebooting before I can get in to bios. Got it to load OS a few times and it would run for like 10 min then reboot cycle. But 95% of the time it just reboots before I could even try to get into bios.

Other peoples fixes that I have tried:
jumper reset cmos
button reset cmos
battery removed cmos reset
tried the 1 ram stick at a time
tried running out side of case on a cardboard box (still reboot loop)
Unplugged everything except the cpu, ram, and gpu.


Specs:
CPU: Intel Core i7-5930K
GPU: EVGA GeForce GTX 980 Ti
Mobo: ASRock Gaming Fatal1ty X99X Killer
RAM: 64 GB CORSAIR Vengeance LPX DDR4
PSU: Thermaltake Toughpower 1275W Modular Power Supply

Anyone got any ideas on how to get this fixed?

Try starting the board with only CPU, CPU cooler installed, both 24 and 8 pin power cables connected. No other components/wires.
Use a screwdriver for shorting the 2 pins corresponding to the case power switch.
See if the CPU fan does spin without restarting.

It's watercooled, but the fans on the radiator do spin while running. That trial with just CPU is good. It don't get stuck in reboot.

Now add single RAM module and test again. If no restart, power off, add the graphics card, start again and see if any signal.

 

[SKREEBUS]

Single stick of ram failed. Tried different sticks and still failed. Tried different slot and failed.

Mobo with no ram and just GPU runs but no signal.

 

[alexoiu]

It might be that you're not inserting the RAM all the way in? Are both latches in locked position? Try pushing a bit harder (without damaging the board).

 

[SKREEBUS]

Both latches were locked in.

Try testing the board outside the case. If still the same, I'd check the CPU socket for bent pins.

 

[SKREEBUS]

Been testing outside of case and this cpu is a pin less cpu so no bent pins and socket is fine too.

 

[alexoiu]

Can you post pictures of the socket and board?

[alexoiu]

Pins look ok. Is the board outside the case?

 

[SKREEBUS]

Yes board is setup on a cardboard box outside of case. Did that to test that it wasn't the case causing a short.

 

[alexoiu]

It might be a board issue then, but I'm not sure. I'd RMA both board and CPU.

 

[SKREEBUS]

But what would cause two different CPUs, two different sets of ram, two different mobos, two different PSUs, and two different GPU's to have the same problem?

 

[alexoiu]

A CPU cooler issue?

I have the same MB and have the same issue. Was there ever a solution on this thread? I am able to get a clean boot by removing the clear cmos pin and holding down the onboard power button to break boot loop. When the computer does boot clean (about one in every 50 boots) it takes a extremely long time to get bios splash screen, like 30-45 seconds
