BIOS not starting, black screen

HP Recommended
p6-2400ec (PN:D7A46EA#BCM SN:CZC3217CMZ)

Hi, I have a problem after replacing the HDD (the original HDD has broken down, so there is no BIOS recovery on the new HDD) that the computer will turn on, but the BIOS remains "dead". The monitor is a black screen. I've tried all the tutorials for this problem on the HP website, but nothing helps. There is no way to get into the BIOS as HP writes. The BIOS recovery could not be created because I did not find any such file for this model. The PC is not mine but my colleagues. He changed something in the BIOS after replacing the HDD and has been in this state ever since. Is there any option for BIOS recovery of this PC? .... in addition to all the options written on the HP support site.
