PANTALLA NEGRO - BLACK SREEN

[jorgebajo]

Hola tengo problemas de arranque. Actualicé BIOS desde la web soporte de HP y desde entonces, el ordenado no responde. He intentado la solucion de aplicar tecla windows+B y reinstalar a traves de unidad USB la BIOS y, aunque llega al final, me aparece en el ultimo paso un error 500. He intentado aplicar tecla windows+V y al terminar, aparece un error 501. He dejado desenchufado el ordenador y apretado el boton 15 segundos y nada. No se si el problema viene por la nueva BIOS instalada o por si al instalar la herramienta UEFI de gestion externa he provocado alguna incompatibilidad. ¿Podeis ayudarme? Gracias

Hello, I have starting problems. I updated BIOS from the HP support website and since then, the computer has not responded. I have tried the solution of applying windows key + B and reinstalling the BIOS through a USB drive and, although it reaches the end, an error 500 appears in the last step. I have tried applying windows key + V and when finished, an error appears 501. I have left the computer unplugged and pressed the button for 15 seconds and nothing. I don't know if the problem comes from the new BIOS installed or if installing the UEFI external management tool caused some incompatibility. Can you help me? Thank you and sorry for my english
