Veldmuus, have you tried an external monitor and does that display properly?

Hi,

I would recommend you to take your laptop to a technician or local repair shop as writing BIOS needs tools and your motherboard might got disintegrated in the process and then put back. However if you mean you have tried flashing it yourself then do the same process to write your backup copy of flash if not then take it to a professional.
