Asus dark hero startup issue ?

Hi all
I have a Asus Crosshair VIII DarkHhero ...with an AMD 5900X , 32gb of Gskils ram

Had a few times over last few months since recieving board where the system wont power on.
You press power switch on case and nothing .
You press power button on motherboard ...nothing ....and its lit up white ...all rgb is working ( on when powered off )
If i turn off PSU and back then power it back on ...system boots fine.
It can then be fine for say 4 weeks ...then happen out the blue again.
Was ok with old motherboard....so only things that have changed is MB and CPU.

Tried reflashing bios back to earlier version ...no different.
Had new graphics card since last time so rules that out.
Tried taking ram sticks out ...no difference.

Seems starnge how can run for weeks without issue ( but dont use it every day )

Im using an EVGA supernova 850W PSU.

Not major issue as all have to do is power off PSU and all good again ...but got to be something wrong.
Asus say sounds like something tripping PSU protection ...will have to try unpluging 24 pin and 8 pin cables next time , then plug back in to see if motherboard or psu .

Any help most appreciated.

I too have the same power on problem. So sad to see inaction from Asus on this. Make it right and initiate some sort of recall/exchange for this motherboard. I will definitely stay away from Asus in the future. Shame.

Asus said...
The impact of covid-19 epidemic is longer than estimated, and we still discuss the replacement program with our local team. I'm sorry the estimated time would be delay until the beginning of July. I will keep you updated if it is early or delayed.


I don't see the problem. There aren't many customers that know about that program. Okay, maybe there will if the program will be public, no idea.

I am also having the issues described here but with the hero wifi board. Shame that ASUS are doing this to their customer, especially on a high end product. Unfortunately I did not find these posts before I bought the motherboard... So I guess on the chance that asus actually gets this "replacement solution" in place i will get a used refurb board that is likely older than the one I currently have as mine had this issue out of the box. does anyone think we will get answers to what is actually wrong? will this issue affect the life of the board? if so does the fix solve that? why are they being so tight lipped about what the issue/fix is? do yall think that the life of the board will be affected fixed or not and this is why they are not being open about the issue? or maybe that the fix involves them disabling/tweaking some function of the board and they know that is unacceptable?

whatever the case something shady is going on it seems. If they continue to refuse to offer an acceptable solution and stall for time what is the re-course we have for dealing with it? I have been posting about this to all the large youtube channels in hopes that they will put some pressure on asus for their unacceptable "replacement solution".

For me, the startup issue is gone after applying bios 4201
The "sudden death" issue (blank screen, q-code led "00" and yellow dram q-led on) is still there.

No it wouldnt solve it, it is a hardware defect, no bios update can fix it.
Just keep trying the issue will re-occur.
It helps to let the PC run maybe a game or something for 30 min and then try until it occurs.

Correct, that was even confirmed to me by the technical/DEV team, they have found the issue on my MB. but i have no replacement yet they need more time.

Did they say any more details about it ? Is this something that will eventually brick the motherboard? Or will it just have this behaviour without getting worse

at least you guys can power cycle and start the pc up

i cannot start the pc up, not from case power button nor the button on the mobo

power cycle the psu does not work, ram, aio rgb on, start button on the mobo is lit, but both the ROG rgb near the io shield and the chipset asus eye logo dont light up

The big question:

Does this problem appear on every board? Or is this random? And has this been fixed for newer production dates?
So getting a new board from the retailer could fix this or not.

Would be great to know.

Hereby an update:
Retailer send the MB back to Asus repair center in EU after consultation regarding the random/intermittent boot issues.
The first time, the retailer just swapped the MB for a new one, the same issue occurred again on the new MB, this time the retailer send the MB to Asus Repair Center.
It took almost 3-4 weeks before I received the MB back, it was the same MB no refurbished by the way.

Comment provided by Asus Repair center towards retailer: We have replaced the chipset on the MB for a new one!

I'm guessing this is the chipset served as a middleman between the CPU and other components.
So far no boot issues have been observed! Hopefully the issue has been resolved! By the way I'm only using shutdown, have no use for PC sleep never tried or tested before.

Hope this helps somehow.
