Hi,

Like I said, if I actually get the computer to either sleep or power off then I can wake up or power on without issues. The problem happens at the moment of puting it to sleep or powering it off. I notice this because in the case of trying to put it to sleep the ram leds turn off while the pcb leds, rog logo, start button remain on. So i basically power cycly the psu right at that moment and i will be able to power it on. I haven't left it like that for any period of time but on sucessfull sleep or power off i've left it like that for maybe 5-6 tops.

I'll probably RMA the board during the weekend and will send you the information requested.

Please update bios 3801 and restore bios to all default settings.
Thank you.

It happened today again and it was pretty much right after I put it to sleep.

Last night it happened. I put it to sleep and tried waking about an hour and a half later.

Hi hakai,
Thank you for your reply.
If you get the RMA number, please send me PM for the serial number and the RMA number.
Thank you.

Hi JerJer123,
Did it occur recently or after you built back in February of this year?
Have you updated bios 3801 and restored bios to all default settings but still occurred?
Thank you.

Here to report the same issue that everyone else here is reporting. I recently switched from an Aorus X570 Master board to the X570 Dark Hero. Everything else in the system is the same and I've had the system up and running for over a year. I never had an issue with startup or powering on before switching to the Dark Hero. I switched to the Dark Hero for some of its additional features beyond the Aorus board. I'm pretty disappointed in this issue.

I've had the Dark Hero board installed for almost two weeks now and everything has been working great until this issue started 3-4 days ago. Before this everything worked great. I first noticed that it would not start back up after being shutdown for a few hours. Since then i've troubleshooted and I have the same issue no matter how long the computer is shutdown. The RGB lights on the I/O panel and Chipset are illuminated but pushing the computer's power button does nothing. I also tried pushing the "Start" button on the board and that likewise does nothing. I even tried jumping the power on pins on the board and nothing.

Changing ERP to S5 fixed the issue for now but based on others comments that is only a temporary solution. To me it sounds like Asus released a bad batch of Dark Hero boards all suffering from the same issue.

I purchased the board from Newegg on Sep. 24, 2021 and just submitted an RMA but am waiting to hear through this forum if there is a solution beyond sending in my board and having no computer while I wait for the replacement.

Here are my system details:

Mobo: Asus x570 Dark Hero (Serial No. M7M0KS160819EVN)
CPU: 5900X
RAM: G.Skill Trident Z Neo 3600 (F4-3600C16D-16GTZNC)
GPU: EVGA RTX 3080 FTW3
PSU: Corsair HX1200i

Old board (now @ RMA) SN: M7M0KC3782619SN
New board SN: M7M0KC208304BLD

Not sure if the new board is from an earlier batch.

Anyway... still no problems with the new board.

Hi DarthPlagueis,
May I double confirm does it occur after you showdown the pc every time? even just shutdown for 10 minutes?
Do you adjust any settings in bios or all default setting?
Have you tried other power supply?
I'm afraid our tech team cannot reproduce the issue with the motherboard on hand.
If you have submitted an RMA, could you please share the RMA number to me?
Thank you.

It happens every time, no matter how long the PC has been shutdown. It won't start again even after 10-30 seconds of being shutdown. The same is true when its been shutdown overnight.

No I have not tried another power supply but am not going to. I did not have this issue on the Aorus x570 motherboard with identical components. And others have reported no changes with a new PSU.

I have not changed any settings since this first started. In other words, this issue did not occur following any BIOS changes.

Here's my RMA number with Newegg. They are shipping me a replacement board so I have not returned the old one (since it still works fine minus the power off issue).

RMA #: 119018760 (Newegg)

Hi DarthPlagueis,
Thank you for your reply.
Could you please let me know if have returned the old one to Newegg?
Thank you.

So just an update:

I submitted my issue to Asus support and they recommended I upgrade to the latest 3801 BIOS for my MB (X570 ROG Crosshair Viii hero WiFi). I upgraded and have not had the issue so far. I've put my PC to sleep multiple times - probably around 20 times straight - and it woke up every single time. Not sure if this is a fluke, but maybe the BIOS update fixed it for me. Fingers crossed. I recommend updating your BIOS to the latest version to see if this helps you. I will probably give another update here in a few days regardless of if it happens again.

Good luck.

Just going to add my Dark Hero to the club....
This issue seems to affect a large amount of Dark Hero boards
Discussions about this issue are all over the Internet in most of the popular pc tech forums.
My Dark Hero won't turn on from power down or sleep, UNLESS I have both S4+S5 enabled in BIOS.
With that setting it turns on without any issues no matter if Powered Off, Sleep or hibernation.

Could Asus increase the priority of this issue please ? Having a premium £400 motherboard not turn on is a critical issue that might result in a recall considering the scale of the issue affecting hundreds if not thousands of boards.

Do we know yet if this is definitely a hardware manufacturing fault or is this fixable with a BIOS update?

Could Asus please respond and suggest a solution ? It has been months !

Hi JBROG87,
Did it occur every time from power down or sleep? regardless of how long it power down or sleep?
Have you tried bios all default settings and other power supply?
May I have the bios version and the components list in your pc?
Thank you.

Hello, i have switched from gigabyte "Aorus Elite" so from one of the cheapest Mb to one of the expensive Dark Hero

and the expensive has more issues shame on you ASUS

I had the same problem, it does not start but i cant see a problem, and i have a M8 Serial number i think its relaticly new produced :mad:

The 3090 strix oc get no 500w bios the bugs from the expensive Mb get not fixed, I'm starting to wonder why I still buy asus

if i get not that fixes and all the voltage fixed that this dark hero needs i think asus had a hard time with me and the future.
and i will convince all my friends who all buy asus that they should better leave it.

i know many from "chaos computer club" and they say this bios looks really mess inside FIX IT !

5950x + 3090 Strix oc

ROG Crosshair VIII Dark Hero Bios = 3801

@STARRAIN

Hi any news on the issue? This tread is getting bigger and bigger, same questions are being asked, but we have no updates on the issue if its being fixed.
Did you guys managed to reproduce the problem?
Thanks

Short update: Still no problems with the new board.

Joining the club as well. Crosshair VIII Extreme that has the symptom described in this thread as if my understanding is correct.

Upon shutdown the PC does not boot. To resolve, the PSU must be manually power cycled: flip the PSU power switch to off, wait for mobo lighting to fade, flip the PSU power switch to on, then press power button on case or start button on mobo. PC boots normally.

Running the latest BIOS release available on rog.asus.com for this board (Version 0402).
New build, 2 months old. This issue began ~1.5-2 weeks ago, just outside of Newegg returns/replace window.

I don't think it was every time, but very frequent, to the point that using sleep function was pointless.
with Default BIOS settings.
I am using Ryzen 9 5950X, 64GB G.Skill Trident Z Neo CL14 3600mhz Ram, Samsung 980 Pro 2TB, Seasonic Prime TX 1000 Platinum Powersupply.

bios version 3801
Have no tried other Power supply, as we all know this is a motherboard issue, nothing to do with power supply.
Enabling S4+S5 mode in Bios fixes the issue and motherboards boots without any issues every time regardless of power off, sleep or hibernation

Have you not received RMA boards back yet? Have you not replicated this issue yet? Have you not made any progress on this CRITICAL issue yet?
We need answers Asus, or you will be swamped with RMAs, believe me

It appears to be a hardware fault then? Manufacturing fault?
Asus, can you comment ?

I replaced the 2080 TI with a 3080 TI on 20. Oct. 2021, which would be ~5 days before my initial post here.
I am however a bit hesitant to RMA the board as of now, as the system is working fine otherwise (an was working flawlessly before the graphics card replacement).

Since Oct. 26th I ran the system with "nearly default" settings

(BIOS defaults +
- AI Overclock Tuner: D.O.C.P. standard
- SVM Mode: Enabled
- Boot / Secure boot / OS-Type: Windows UEFI Mode
- Advanced / AMD fTPM config: Enable Firmware TPM
- Resize BAR: ON
- Download and Install Armory Crate App: OFF)

and had so far 2 failed starts out of 8 reboots, which seems less frequent than before with my original bios settings (4 failed out of 6).

Hi all,
Although some customers have returned it to retailer or sent RMA, I'm not sure when the retailer or distributor will send it to our repair center.
We haven't received the motherboards for testing so far, but I will keep follow this case.
If the issue occurs often on your ROG CROSSHAIR VIII DARK motherboard, and the bios is updated to 3081 with all default setting but the issue still occurs, could you please send RMA and PM me the following information?
- the serial number and RMA number of the motherboard
- How often do the issue occur? cannot wake up or cannot start up?
- bios version and bios settings
- the pc specs of the pc
Thank you very much.

Hi Sackdragon,
Because the model is different, could you please create a new thread for discussion?
Thank you.

Good day to all. Sorry for my english, I am using google translate. I confirm the problem with the dark hero motherboard. My configuration is thermaltake toughpower grand rgb 750 80 plus gold standart, cpu- 5800x, vga-sapphire 5700xt nitro +, ram-4 * 8gb Corsair Vengeance RGB Pro CMW32GX4M4C3600C18. Default bios settings, version 3801. s \ n mb M7M0KC122044BX4. I have not experimented with the settings in bios S4 + S5 yet. I do not take the computer into sleep mode, I just turn it off completely. All of these components on the ROG CROSSHAIR VII HERO motherboard worked fine. I think you need to admit that there is a defect in these motherboards or fix this problem in the next version of the BIOS. Thanks.

Hi lexis-ermakov,
Do you also face not startup issue after shut down and have to turn off and turn on power supply to boot?
How often do the issue occur? Do it occur every time you shut down the pc?
Thank you.

Well, it's been almost 4 days since I posted this and I guess it was too good to be true. The issue occurred last night once again. Put my PC to sleep and left the house for about 1.5 hours or so, came back, tried to wake, keyboard lights flash, RAM RGB is off (it is usually on when it wakes successfully), and "Hero" text on MB is illuminated. Had to switch power supply switch off and on to be able to boot back into system.

This is very frustrating.

Hi all,

I'm also having this issue with my Dark Hero since I built my new rig in June. I'm not using sleep mode, so I only have the issue that both the power button and the "Start" button on the mainboard don't work sometimes. I have to switch off the PSU then.

By enabling stealth mode in the BIOS, you can predict immediately after shutdown whether the power button will work. If all lights are off, the power button will work. If the "Start" button on the board is lit though, pressing the power button or the "Start" button has no observable effect. Enabling/disabling stealth mode does neither improve nor worsen the issue. It's just a good issue detector and a hint that something seems to go wrong during shutdown.

I've updated the BIOS twice since June and I'm using 3801 now. Back in summer the issue did occur more often than now. In summer it occurred approximately 1 out of 3 times, now it's more 1 out of 10 times. I'm not sure if it's the BIOS update, the lower ambient temperature or the fact that I don't play hardware demanding games recently. Although I tried I did not find a way to reliably reproduce the issue.

My specs are:

Asus Dark Hero (BIOS 3801)
Ryzen 5950X
128GB RAM 3600MHz (HX436C18FB3K4/128)
Asus RTX3090-24G-EK (BIOS V4)
Corsair AX1600i PSU
Samsung SSD 980 PRO 2TB (NVMe)
Both D-RGB Header are used

Just going to RMA the board. Doesn't seem like this is going to get fixed through software.

Yes, everything is exactly like that. Short-term shutdown (10-30 minutes) everything is fine, if 8-10 hours it does not turn on. Capacitors?

Hi all,

I can also confirm that I have experienced this issue; now on two Dark Hero boards -- very disappointing.

In June I assembled a new system using the Dark Hero as the basis. I immediately experienced the problem described in this thread: that occasionally after shutting down and/or going to sleep the machine could not be started again (by the power button, keyboard, etc) without isolating the PSU from the power source for sufficient time for the motherboard to fully discharge -- then the PC could be started again as normal. This would happy approximately 1 in 10 power-down or sleep events.

I contacted local Asus support (Netherlands) and discussed the issue. They suggested that I return the board to the store, as it was new. I did so, and got a refund. I then bought the same board (Dark Hero) from a different vendor -- the issue was instantly resolved and I could not replicate the problem again after weeks of use.


Unfortunately, after around three months of using the new Dark Hero board, the same issue has begin to re-appear. Very sad.


Edit: to clarify -- during this ordeal, to make doubly sure the motherboard was the issue, I've independently swapped out everything else in the system one-by-one and can reproduce the issue. Everything except the CPU (as I don't have another CPU or X570 MB to test). But there are not other issues in regular use, under load or otherwise

The fact that this issue appeared again after some time makes me think it is probably some kind of hardware degradation, but I suppose it could still be something odd in the BIOS firmware. [I'm a computer engineer and design medical systems for a big tech company -- just my intuition based on experience]

I could return my current board for replacement again but since this is my second board, I have become doubtful that the replacement will resolve issue. Is it just going to occur again after some time? I would like some more insight from Asus before I waste more time on disassembling my PC and waiting for RMAs. I have the feeling that, if this is a hardware issue, it is a fundamental design flaw.

[As a side note, and as someone in this thread already pointed out, you can observe immediately whether the power-down/sleep failed: by setting the motherboard aura lights to be in 'stealth mode' during sleep/power-off (bios setting), all of the lights should go out during a successful sleep/power-off -- in the case of this failure, the 'start' button light on the motherboard remains on immediately, indicating that this fault has occurred and the system will not restart in either a power-down or sleep. At least in my experience, the fault does not occur as the result of accumulation of time after sleep/power-off but immediately at the moment of the power event.]

@ASUS: do you recommend that I spend time returning this board again? Do you have confidence that board number 3 will be different from the others? i.e. Has any relevant issue been resolved in production that could affect this?

By the way, in the first round of my 'dark' experiences, I discovered that this exact issue is not only affecting the Dark Hero boards but also similar boards, take for example the regular 'Hero' variety -- you can see a nice documentation of exactly the same issue below:

https://www.reddit.com/r/techsupport...ifi_wont_post/

Chipset issue? Common shared components? Common BIOS issue?

This is a very specific problem that seems to not be very rare, and even recur on multiple boards for a single user (see my previous post). Asus need to take this seriously or risk alienating loyal customers.

Thank you so much for posting be this. The poster also provided a video which is exactly what I've been experiencing:

https://www.youtube.com/watch?v=HfiNIuq048A

I've already RMAd my motherboard, but hopefully this can provide some insight to Asus staff

Hi von_nihil,
Does the issues only occur with stealth mode or occur with bios all default settings as well?
Thank you.

Hi JerJer123,
May I have the following information via PM?
- the serial number and RMA number of the motherboard
- How often do the issue occur on bios 3801? 40%? Did it only occur on sleep mode or you also have the issue after shutdown?
- Did it occur with bios all default settings?
- the specific model name of ram such as G.SKILL F4-3200C16D-32GTZA
- Have you tried other power supply or other components?
Thank you very much.

Hello Von Nihil,
Thanks you for your great feedback. I get the same issue untill I changed the board with RMA. Since no more booting problem.
You scared me a lot with your 2d board who bugged after 3 months...
I think you"r right with the componant degradation theory. My first board destroyed the CORSAIR RAM I used. The 4x8 corsair ram was working perfectly with my old setup. Just after being plugged in the first board they were instantly broken (crashs, and failed memtest....) Here my post :
https://rog.asus.com/forum/showthrea...vent-code-144)

Can you tell us what's the QCOD of you'r motherboard ?

It occurs in every BIOS configuration that I have tried. This includes 'optimized defaults' and a lot of other experimental variations. The only significant factor in stealth mode is that you can observe when the fault has occurred immediately by noticing full stealth-mode was not reached ('Start' button light remains lit).

This thread was started end of July.... It has been almost 4months since this issue was reported, many boards have been returned with RMA since then.

Still no progress? Still not able to reproduce this problem? How long does it take you to check returned motherboards, half a year ???
It's not just the Dark Hero, the issue also exists on the Hero and Hero wifi boards, 3 different boards all plagued by the same problem.

Come on Asus, could you please finally address this issue?? This is not a small stability issue, PCs literally fail to turn on.
If you were a car manufacturer you would be out of business by now.

Hi STARRAIN,

I guess I should clarify. I recently shipped my MB back to ASUS for an RMA. We'll see how it turns out.

Good day,

Just wanted to leave a follow up here. My board should be in the service center since last week. So far I’ve only gotten automated messages stating the estimated completion date but have gotten 2 more emails since delaying the date. Status is just shown as diagnosis/repair. Starrain@rog do you know if this is being looked into? How are they testing the board? Replicating this should be straightforward.Â*

I keep seeing more and more cases for this issue pop up which quite frankly is concerning and I am getting frustrated as their is no recognition by ASUS that this issue does exist. Â*

In case you need it again:
Â*RMA Number: USPCMA5269
Serial Number: M7M0KS045631WHLÂ*


Please give us an update. Â*

Hi JerJer123,
I know you have sent RMA, but I need some information for internal tracking.
Could you please share the information to me via PM?
- the serial number and RMA number of the motherboard
- How often do the issue occur on bios 3801? 40%? Did it only occur on sleep mode or you also have the issue after shutdown? If you put it to sleep mode and wake it up immediately, does the issue occur?
- May I know the temperature at the place you put the pc while the issue occurs?
- Did it occur with bios all default settings?
- the specific model name of ram such as G.SKILL F4-3200C16D-32GTZA
- Have you tried other power supply or other components?
Thank you very much.

Hi von_nihil,
Thank you for your reply.
Do you remember the serial number of the old motherboard? If yes, may I have the serial number via PM?
If you shut down or put it to sleep mode and then turn it on or wake it up immediately, does the issue occur?
May I know the temperature at the place you put the pc while the issue occurs?
Thank you.
