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!
Solved! Go to Solution.

Hello, @bwandowando
After some time, may I ask if you had any overclocking settings in place during this period?
When the system automatically shut down and could not power on, what was your usage scenario at that time, and have you ruled out potential overheating as a cause?
If the issue has not occurred again, we recommend continuing to monitor during usage.
Thank you.

Hello @Jiaszzz_ROG
Aside from enabling XMP, I haven't done any OCing and I've always been using Stock and default settings
When the system automatically shut down and could not power on, what was your usage scenario at that time, and have you ruled out potential overheating as a cause?
I was just running some Python processes, no gaming, no benchmarking, minimal load. It just... shutdown and the glowing LED of the motherboard can be seen. But it can't be powered on. I had to do a CMOS reset just to be able to power it back on.
If the issue has not occurred again, we recommend continuing to monitor during usage.
Yes , I will monitor

I have the same problem, I’m in Mexico but for some reason they told me that US warranty should be reached and when I contacted them they told me that I need a US address…
I tried clear cmos, it worked once, now it’s not working anymore, idk what to do it just wont boot up I have been having this issue for a month, sometimes boots up, sometimes it doesn’t.

I join the party. Since this week, I get the exact same issue from nowhere with my STRIX Z790-A GAMING WIFI D4.
When the PC is shut down, the green light of BIOS FLBK blinks constantly and I cannot restart the computer, nothing happens when I push the on/off button. I have to unplug the PC from the outlet few seconds, replug it and rapidly push the on button.
This is the same thing with hibernate. However, this issue do not happen when using reboot or sleep function.
I already tried another PSU & RAM, unplugging some USB cables, resitting the CPU, clearing CMOS, reflashing the BIOS, disabling "ERP Ready", etc. Nothing improves the situation..
Funny enough, this issue was already reported few months ago with this motherboard : Z790-A WIFI D4 : FLBK LED blinks green continuousl... - Republic of Gamers Forum - 989908 (asus.com)
Asus should start to take this seriously as several people face this issue.

Anyone else downloaded and applied the latest firmware?
I just did.
Ill post updates every now and then about the performance and stability of my system, as well as if this would address the issues I we are encountering

I have installed the latest UEFI update. It runs smoothly and stably for me. But I have never had any stability problems with my hardware.

Hello inge70
I dont quite understand your reply. You said it runs smoothly and stably, but you're having hardware stability problems? Doesn't that mean it doesn't run stably at all?
Anyway, I do hope that this firmware would fix my stability issues, on the other hand, i do hope that ASUS would release a new firmware that would help address your stability concerns.

Sorry, something was translated incorrectly.
I have never had instability problems with my hardware.

This problem still persits for me, even after updating to the latest firmware (Version 2503).
Just as before I can only start the computer by Clear CMOS on the back side, also got another BSOD 2 times during the last 24h. Still investigating why.
I've never been this sick and tired of a MB before.

What kind of hardware do you have exactly?
As I read in an earlier post from you, the problem suddenly appeared in May.
What did you do BEFORE the problem occurred, did you set something in the UEFI/Bios or flash a newer UEFI update?
If you reset UEFI via CMOS, you go back to UEFI after a new start, save it and start Windows, right?
Do you change anything in the UEFI or do you just save the basic settings that are set via CMOS?
If you get BOSD'S, then your problem may be due to your Windows installation and less to the UEFI/Bios update, because after a CMOS, the UEFI is usually switched to UEFI boot with GPT partition table. But if your Windows was not installed in GPT mode, then the PC won't boot or there will be BSODs if there are other errors.
