Question No display in brand new pc build. Orange DRAM light.

[Ulicon]

I just built a brand new case but although all RGB's and fans are working, there is no signal on the screen. I changed the ram slots and tried with one ram, I reset BIOS and did BIOS flashback with 2 USBs, cleaned GPU and ram with an eraser.
System:
ASUS ROG STRIX Z690-A
INTEL I7-12700KF
CORSAIR VENGEANCE RGB PRO SL 2X16 3600MHz DDR4
MSI SUPRIM X RTX 3070TI
CORSAIR H150I ELITE CAPELLIX
CORSAIR 5000D
SAMSUNG 970 EVO PLUS M2 1TB
CORSAIR CXF 750W
