Hi [NAME],   It seems to have corrupted BIOS, if might need a mainboard replacement. Try unplug the power cables, press and hold the power button for 15 secs. Install the power cables back and turn on the server. Check if the issue persist. If it does, remove all components except the below and turn on the server to check the issue. Try another monitor. If all fail, there is no other steps to restore the server, unfortunately, you need to replacement the mainboard.
