Asus Z790 Gaming Wifi7 only fully boots after turning PSU power switch off and on again.

[bcoli2674]

I'm currently using the gaming wifi7 mobo in a new NZXT H5 Flow.  Pressing the power button on the case will turn it on, I see the bios screen, and then instead of fully booting up, it doesn't seem to  recognize my monitors.  My GPU is an Asus 4080 Super. 

Only when I switch the power off at the PSU, wait about 10-15 seconds to flip it back on, and THEN press the case button does it fully boot up as if nothing were wrong:

System info showing all components, UserBenchmark recognizes and tests everything, playing AAA games on max res doesn't affect anything, etc.

Also: If I just enter BIOS and I do (or even don't) make any adjustments, when I press F10 to exit, the same problem occurs.

Hello @bcoli2674 

Thank you for reaching out to us.
May I ask if the issue occurred after you switched to the NZXT H5 Flow chassis, and it didn’t happen before?
When you press the power button on the chassis, does it boot into the BIOS but fail to enter Windows?
If possible, please provide more detailed hardware and software specifications, such as the BIOS version and related settings, the specific 'fail to boot' scenario, and whether there are any abnormal Q-LED Core indicators during startup.
If so, please refer to the relevant guidance in the [Motherboard] FAQ of Q-LED Core.
Based on the current situation you’ve described, we recommend referring to the Z790 GAMING WIFI7 User’s Manual to ensure that all hardware components, including the system drive, power cable, and front I/O connector, are properly connected and clear CMOS before checking again.

Thank you.
