I didn't see the usb on boot menu so i changed boot settings. 1 boot OS SATA, 2 usb devices. All others disabled. After this i get no display signal, no mouse or keyboard signal even using an PS2 port. GPU is RTX 2070 ti.

I've tried removing motherboard battery and pressing power button for 30 sec but no success. Also detaching all HDD ssd and usb connected devices, removing ram and using only one stick. No success.
