Asus x99 Pro USB 3.1 MB QR errors. What is going on?

Level 7
Hi everyone!!
I am new in here and am in great need of help.
After completing my rig in late 2015 I recently started experiencing issues with my MB. Over the past 2 months my PC has been acting strange. I never OC and I do have a liquid cooler installed. Here are my components:


Intel - Core i7-5820K 3.3GHz 6-Core Processor

CPU Cooler

Corsair - H110i GT 113.0 CFM Liquid CPU Cooler


Asus - X99-PRO/USB 3.1 ATX LGA2011-3 Motherboard


G.Skill - Ripjaws 4 series 32GB (4 x 8GB) DDR4-2800 Memory


Samsung - 850 Pro Series 512GB 2.5" Solid State Drive

Western Digital - Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive

Video Card

EVGA - GeForce GTX 980 Ti 6GB Classified ACX 2.0+ Video Card

Thermaltake - Core V71 ATX Full Tower Case

Power Supply

EVGA - SuperNOVA P2 850W 80+ Platinum Certified Fully-Modular ATX Power Supply

Optical Drive

LG - WH14NS40 Blu-Ray/DVD/CD Writer

Operating System

Microsoft - Windows 10 Pro OEM 64-bit

Case Fan

Thermaltake - Luna 12 LED 50.4 CFM 120mm Fan

Thermaltake - Luna 12 LED 50.4 CFM 120mm Fan

Thermaltake - CL-F036-PL14BU-A 38.6 CFM 140mm Fan


Dell - U2715H 27.0" 2560x1440 60Hz Monitor


Logitech - G510 Wired Gaming Keyboard


Logitech - G502 Proteus Core Wired Optical Mouse

Here are the symptoms:
1) The PC is only able to post after I pull the 3V battery out and move the jumper to clear the CMOS. --> Everything Works. (Or power cycle the PSU)
2) After post, Windows loads and I am able to use my PC
3) Then the PC goes to sleep. When I decide to bring the PC back from sleep it simply receives enough power to restart once and show all kinds of QR codes: 00, a6. Sometimes it continues restarting while showing (00).
I really don't know what to do anymore. Right now, my PC is running w/o any issues. Is it really the CPU issue? If yes then how come I am able to boot up windows after clearing CMOS?

The issue only appears after bringing the PC back from sleep and also when it is completely shut-down. (How come issue dispersal after I clear CMOS or power cycle PSU?)

Lastly, I would like to add that I took everything apart to bare minimum to test each component outside of the case. I started with MB and PSU w/o CPU. Then I was adding each component 1 by 1 and trying to replicate the issue. Luckily, the error did not appear. Unfortunately it did this morning, Code 00. Please help me out, I am total noob so have patience with me.
Thank you.
