Lenovo C50-30 no boot, black screen after bios "load optimized default"

Hi everyone !!!
After the last update of Windows 10, I had 3 Lenovo C50-30s which, on rebooting, remained still on the Lenovo sign.
After finding the solution, in the various attempts made, on one of these I did top up the default settings of the bios: from that moment the pc doesn't start, black screen, no response from the keyboard.
I have already reset the bios from motherboard, but nothing to do, the PC as soon as it receives power turns on and does nothing.
By removing the ram instead it goes into alarm, but if I try to replace it with another return to the starting situation.
What may have happened ?
