Re: Elumatec E555
I not familiar with that controller, but I can give you some general computer advice.
The symptoms you describe sounds like a power supply problem. I would first remove any accessory cards from the motherboard and see if it will at least power up. If not then replace the power supply. I'm assuming that it will run on a standard AT or ATX power supply
When you reset the BIOS that possibly changed the boot order, or would maybe require that you reenter the drive parameters, so it didn't know where to look for the boot drive. There should be a jumper near the CMOS battery that would allow a BIOS reset. I can't imagine a monitor not coming up do to a BIOS setting in any kind of a Windows based system.
