Gigabyte z790 pro x wifi7 5 short beeps

[prideshellsuit]

Gigabyte z790 pro x wifi7 5 short beeps then stuck on black screen, never display Gigabyte logo, never boots into windows 11 only when I connect all 4 monitors to the asus gtx 1070. Work around when I disconnect 1 hdmi monitor from the asus gtx 1070 then plug this 1 hdmi monitor directly to the on board 12900k igpu motherboard hdmi out then computer beeps once then display gigabyte logo then boots successfully into windows 11. Windows 11 sees both asus gtx 1070 and 12900k igpu. How do I keep all 4 monitors plug to the asus gtx 1070 without having to plug in a hdmi monitor directly to the on board 12900k igpu motherboard hdmi out?

Maybe try updating the BIOS and checking the "Primary Display" setting in the BIOS to make sure it uses the GTX 1070. Or check the HDMI cable and power supply to make sure it has enough power.
