Maybe this will work:

Ensure the monitor is connected to the primary GPU ( the one in the 16x slot closest to the CPU )

Disconnect the USB or SSD/HHD from the rig.

Fully power off everything: including the PSU.

Press the power button several times to clear any remaining power in the mobo.

Turn the PSU powerswitch back to | "on".

power on (without the USB attached)

See if the bios posts; if you get nothing in 20 seconds; press ctrl + alt + del repeatedly until the system reboots.

Wait and see if the bios posts.

If the bios posts attach the USB key to a USB 2.0 port and press ctrl + alt + delete.

if it boots; stop the mining process before it starts mining:

then go to the top left and click the ubuntu button

type u

and click on software updater

run updates

reboot

Let me know if this works.

I tried with a new motherboard MSI Z270 Gaming Plus with only one GPU directly connected to it, and a new PSU.
Same Result.
I have extra pendrives but I am not able to copy the image there because they are 15.5 Gb and I it needs 15.6.

If the bios posts; you can access the grub loader menu by pressing

esc

continuously while booting (note holding it down doesn't usually work), then select boot in recovery mode.

in recovery mode:

Enable networking

then install updates from the cmd prompt:

Code:

sudo apt-get update && sudo apt-get dist-upgrade --yes

and reboot

this should ensure your build has all known system files for your system.

I think I've found the problem, it is not solved by updating:
I installed xubuntu in a new pendrive. And did a apt dist-upgrade, after that, I rebooted and installed lastest amdgpu-pro drivers, and then it happended exactly the same.
I am able to press ctrl+f1 and work via command prompt, but it is not solved by updating.
I am still trying to connect the pendrive to the 2.0 USB port, but it is not recognized. Why do you suggest to do it like this?

Thanks for your help!

There is something wrong with your usb image it if is not recognized when connecting to a USB 2.0 port. USB 3 and 3.1 are fully compatible with 2.0.

There may be a TPM or secureboot option in the bios that is causing problems.

I am assuming you are connecting the monitor to the GPU, and not the motherboard (if you connect a monitor directly to the motherboard; rxOC will go into an infinite loop).
