Your Asus Z390 E Gaming board is showing up but not displaying properly after the BIOS flash. Check if the power is stable, ensure the USB drive is properly seated, and verify the BIOS version matches your hardware. Also, try booting from a different USB or a known-good system to rule out corruption.
I checked the situation and everything seems normal; no power loss or issues detected.
Consider removing the CMOS by connecting a jumper called clrtc near your front panel connectors. Connect the pins for about 10 seconds while the PC is off (PSU active) and check if it starts.
Successfully resolved the CMOS issue. Appreciate your support.
