Hi everyone
My first cold boot was successful with post and everything being recognized. While still plugged into the power outlet, warm boots, resets and booting from sleep is successful.
The issue starts once I unplug the system from the wall, I can't boot by simply pressing the power button, I can only cold boot if i hold down the power button for abit and then pressing it once. This powers up the PC just fine. Again warm boots, resets/restarts and booting from sleep is fine and works perfectly..
So I tried to troubleshoot this,
1. By pressing clr cmos on mobo on cold boots, this starts the computer straight away, but issues stiil occurs if I cold boot by simply pressing the power button.
2. So now I turned off the system, unplugged the power supply and pressed clr cmos button. I then plugged the system back in and pressed the power button and it powered up with no long press on power button on a cold boot. So excited, I turned off the system, then unplugged it, this time NOT clearing cmos, I had the cold boot issue again. I had to hold down the power button and then press it again to boot.
Everything seems stable, I have no issues and mobo Qcode is AO (which is good)
My temps are 29-32 degrees idle and 49-55 on load
Please note, issue is only with cold boots.
Can anyone advise what could be the problem here?
My system specs are as follows;
MOBO: ASUS Maximus Hero VIII (Bios 1701)
CPU: i7-6700K @4Ghz
Cooler: Noctua NH-12US
RAM: G.Skill RipJaws V @ 2133mhz
GPU: GTX 1070 Strix
PSU: EVGA P2 850W
SSD: Samsung EVO 850 250GB
HHD: WD Blue 1TB
Optical Drive: ASUS BT
CASE: Corsair 760T V2
I hope to solve this issue - Thanks!
UPDATE 1: I updated the mobo to BIOS 2202 and still have the issue on cold boots 😕

I have noticed that cold boot issue too! Sometimes (not always ) when you completely turn off the Power from PSU and from the Power Socket on the first Start the System hangs during Windows Post...

I was having exactly the same issue. Machine ran just fine but once I pulled the PSU, re-plugged it, my PC wouldn't turn on anymore. In addition, if I could get it to boot then BIOS date/time were off (displayed the time I unplugged power) and my settings were gone and I had to do them all again - once booted, the machine was stable and had no crashes or anything of that sort. Thought it was an issue with the CMOS battery, so I replaced it with a new reputable one. Frankly, it didn't solve the issue. At some point the issue disappeared, time passed and I had forgotten about it already, until last week, one morning my PC didn't boot immediately. Note: I didn't unplug the PSU and there were no power drops. I can press the power button on the motherboard and it will take anywhere from 5-50 seconds for the computer recognize it. This morning, the PC wouldn't start at all so I got tired of waiting and decided to take it to parts and put it back together - no luck at first, but eventually I got it to boot. I'm so sick of this motherboard. I'm running BIOS version 1202 x64 and am looking to update it to a more recent version. 1902 seems to be stable for most people, so I guess I'll try that and report back. I know I'm shooting in the dark, but perhaps someone more knowledgeable can confirm whether it may have something to do with the room temperature?

Do you get a normal cold boot if you don't unplug the PSU?

Sorry to hear that. I'm in the same boat as you but as money is tight I can't really justify spending another 250 euros for a board that might or may not work.*
In my last reply I promised to write back whether it fixed my issue and the short answer is it did not. In addition to what I described in my last post, I've tried removing RAM and just booting with one stick installed at once with all 4 sticks. Every evening I spend somewhat 15-90 minutes to get my PC booting so I can play a couple of matches. Why won't it post/boot normally? Funny thing is - if it boots, then the computer runs extremely well.*I'm really frustrated!
Off-topic: I've lost my faith in ASUS and probably will never ever buy anything from that brand - my 980 Ti had coil whine OOB, motherboard didn't work properly from day 1. Having paid premium price I expect premium experience - reading reviews on what other people have said, it is just sad that they can't handle QC. Go figure.
