Possibly defective ASUS ROG MAXIMUS X HERO (WI-FI AC) Motherboard

[Mr_Robot_X]

I have a random boot off and on once before full power problem, i cannot resolve, even with an RMA replacement EVGA power supply. My inintal thought was that my 440 days old EVGA Supernova 650W G2 80+ Gold was defective so i contacted EVGA to get a RMA replacement, after recieving the replacement and exchanging it with the old power supply, i still have the boot off and on problem. Now, im left with no choice to assume my motherboard is defective, even its impossible, since i never overclocked it or flashed the Bios with the lastest Bio verision. I have recorded the boot off and on problem and will be sharing the link here below.

I purchased the motherboard on December 29th, 2017, and had it working fine fully until Febubary 18, 2018 when the boot off and on problem started. Also i didn't do the delidding of the cpu myself, i had a guy do it in mississauga for $30, delidding with a rockit kit and replacing the old TIM with Grizzly Conductonaut Liquid metal, and resealed the IHS. His facebook page link is below. I have a warranty from this guy who delidded the i7 8700k on December 24th, 2017 for 3 years, but he told he rarely has a problem with the cilents having a defective delidded cpu, so the defective CPU is not possible, but a defective motherboard may be possible. Overall, i am very annoyed with this problem, altough its not doing any peramenant damage to my hardware parts, but at a $400 CAD paid with taxes for the motherboard itself, its a big a problem. So check out my gaming config below, and let me know what is the real source of my problem, thanks. In the meanwhile, i will be reading the motherboard manual with the QR table to understand the meaning of each code during the boot off and on issue, but i prefer if you guys can explain it for me thanks, its recorded in the link above.

*Update* March 2, 2018 8:55 PM EST --> I remember buying the motherboard from Canada Computers, the cashier opened the motherboard box and opened the CPU protection socket to show proof that there is no bent pins. I checked with my own and saw no bent pins, its confirmed as shown in the reciept image.

*Update* March 2, 2018 10:13 PM EST --> I have reapplied the thermal paste which is the Arctic MX-4 and reseated the CPU cooler, as expected, the boot off and on problem is still there.

*Update* March 3, 2018 3:27 PM EST --> Check out the updated diagnose log of all the possible things i tested.



*Update* March 3, 2018 3:42 PM EST --> I have included the diagnose log for the EVGA supernova 650W G2 PSU, if that helps you figure out the real problem.

I had an Abit ip35-e mobo that did that from the day i built it and it worked fine for 6 years. Abit released a bios that stopped it cause people complained, but it was an actual feature, it was like a power on self check or something. I didn't update the bios because it didn't bother me. Basically you could hear the system power up fans start running then it shut down real quick and started normal.

So you mean its a actual protection feature ? Damn, it was so confusing unti i read this below

It seems that people are saying its a power protection feature, oh well I'm take out the RMA replacement and put back the old PSU back.

It's normal when you have the ERP Ready set to S4+S5. Disable it in BIOS and change the LED settings in BIOS so you LED goes off when the computer is turned OFF

But it never did that before from December 29, 2017 to present until Feburary 18, 2018, is that still normal?

*Update* I checked the bios setting for the ERP Ready, its already disabled, it was never turned on. Also all the LED settings are turned on by default, did you even see the dropbox video ?
