The trick was to disconnect the motherboard from the power supply and plug it back in.

It’s fixed. No because of you, Berny. Knowing what I shouldn’t have done didn’t help me.

I tried to uninstall kapersky. I reset the computer. The screens didn’t have signal. I changed the conectors. It sloved the issue. However kapersky was noy uninstalled. I repeated the operation: run the uninstaller. Again the screen are off. No way to fix them now. The screens are ok, (I tested with my laptop) but there’s no signal going from the cpu to the monitors.
