I have a consultant built 2003 server RAID 5. I rebooted the server after doing the auto updates. Now I cannot get any video at all, the monitor shows no signal. No bios screens or anything. It has a dual power supply and both those light up green. The hard drives are flashing. The network is lit up. I have tried different monitors to no avail. The keyboard and mouse light up fine and the number lock key can be switched. It has an onboard video card.
