ROG STRIX Z790-F GAMING WiFi won't boot up

[Yapper1]

Hello everyone! I have a problem with my PC, more precisely the Motherboard.

The problem is when I shut down the PC. It won't power up at all from the power button or reset or anything, unless I reset the CMOS from the button at the back. Then I get into the BIOS, everything looks OK and if I change anything and try to save the settings, the PC shuts down to reset and cannot be powered up by the power button or anything else. The cycle repeats if I reset the CMOS. The only way to get  the PC to start normally into Windows is to not change anything in the BIOS so it only restarts(not shut down) and then it loads normally. I've updated the BIOS to 1501. I was on 1402 before, tried with 1303 as well, still the same. Tried the flashback from USB, tried the flashback from the BIOS: all results are the same. The moment the PC needs to shutdown(even when updating the BIOS itself) it doesn't boot up. I have to reset the CMOS. What I notice is that the flashback LED keeps blinking even when I don't have a USB inserted in the flashback port or haven't pressed the flashback button after rebooting the PC.

I swapped the PSU - it wasn't it. I did a test on the RAM - it was fine, 0 errors. The Q-LED shows everything is fine when the PC boots up. I ran the tests without the GPU so it isn't that. I tried a minimum configuration with nothing external connected: only CPU, RAM, PSU and Motherboard - all the same. I also swapped the CMOS battery - no change.

My configuration:
Motherboard - ROG STRIX Z790-F GAMING WiFi
CPU - Intel Corei7 13700K
GPU - NVIDIA RTX 4090
PSU - ROG-THOR-1000P2-GAMING 1000W
RAM - Kingston Fury Renegade 6400 DDR5 32GB
OS - Windows 11 (all updated)

Thank you in advance!

Since May 2023 everything has been perfect. But at the end of December 2023, my computer simply turned off while watching a video. And the power button on the case did not help me. It turned on after the Clear Cmos button on the back of the case.
And the next day it repeats. And it may turn off after a few minutes or a few hours. And even in the BIOS.
If you turn off the computer and unplug the power cable, it will only start using the Clear Cmos button.
If you turn off the computer and turn it on without unplugging the power cable, it will start normally from the button on the case.
1. First I tried a different power supply and a video card without it - it didn’t help. I'm currently using the same power supply and video card on a different computer.
2. Tried a new BIOS and a new BIOS battery. - did not help
3. I tried the OSST test at full load - everything is fine, there are no errors and the temperature is good.
4. OSST can simply maintain monitoring of all sensors - and no errors even when it is turned off. (OSST retains all monitoring).
5. Tested the processor and DDR5 on another PC - everything is fine.
6. Therefore, I did not find solutions and sent the Mather Board to the service center and now I am waiting for solutions.

I have seen the same problems with many Asus Z-790 MB. And many problems began in the last few months.

Please let me know if anyone knows the cause of this problem. To avoid this or avoid this MB.

I've been using Asus MB for 20 years and this is the first time I've had problems with them. I am extremely disappointed. (Even My Old Asus Z77-Deluxe is still allive from 2013 and have no problems)

Got exactly the same issue. Started about 2 weeks ago. I have current PC for about a year and everything was fine until recently.

Now I have to turn off PCU, wait for the LED on motherboard to go off, turn on PCU switch and right after that hit Power button - after that PC boots normally and there is no more issues until next shutdown. Issue only repeats after shutdown, but not on reboots or exiting sleep mode.

I am not sure, maybe there was an update for Windows 11 right before this issue began, do not remember exactly. 

Tried stress testing CPU, GPU, memory - no issue.

There were no any hardware changes for the last year after PC was assembled. All BIOS setting are at default values from the start. Did not attempted any BIOS updates/reset so far - everything is in stock condition as it was when I've bought this MB.

I use Intel Extreme Tuning Utility to limit "Turbo Boost Short Power Max (PL2 limit)" to '253.0 W' (default value is 'Unlimited') and I am setting it to the same value as "Turbo Boost Power Max (PL1 limit)" default value to avoid heat spikes as I use air coolers. This IET Utility is loaded after windows boot and its setting are only in affect until reboot so it should not affect power up process.

Except for this frustrating inconvenience with power up process, everything else is working fine.

I have exactly the same problem with my asus rog strix z790  f gaming wifi

It would be very useful if the people from Asus service would come with some clarifications about this because it is really a problem with many motherboards.

I had this problem too with an Asus z790 Strix-A DDR5 board. Was still under 1 year old though so sent it back to Amazon and bought the Strix-A II DDR5 (rev 2) board. Been fine since. I think as someone here said earlier it is an issue with TPM. I updated Windows 11, shut down PC, next morning wouldn't turn back on via case power switch. The only way I could get the system to boot was via CMOS reset button on back of the board. Not sure exactly why this happened suddenly. Seems no one here knows why either. If it happens again with this board I will just send this back and avoid ASUS motherboards completely this time and just go with MSI.

I have the same problem, every time the PC crashes or power cuts I have to reset CMOs for the pc to start.

sometimes it will not start even with a normal restart or shutdown.

I have the latest bios and fresh Win 11.

I have had this M/B for over a year the problem started in the last 2 weeks.

I guess no one has managed to find a solution for this problem, I tried everything I can think of software and hardware but nothing can fix it.

I ended up sending it back to asus for an rma.

Adding to this thread because it's 100% what's happening to me. 

No new hardware, nothing. Just one day, the PC refused to boot no matter what. Changed the PSU, battery, swapped RAM - well I did everything I could and the only thing that let me boot my PC is clearing CMOS from the button on the mobo I/O. 

I can't find any kind of solution and I can't RMA it...

Why can't you rma?
