All we know and you know that some hardware (PSU, motherboard, CPU, RAM, cable or monitor) is broken or incompatibe with the other components if the monitor doesn't show the BIOS-setup when connected with the video output on the motherboard. It's up to a tech to find out which of these 6 is (or are) the culprit. If you can't do that yourself, find someone who can.
