Re: bios help
Rather than writing the bios (rom bios) on the motherboard, Compaq writes it on the hard disk. Since you tried everything and only got a blank screen is because you hard disk is gone and the motherboard cannot access the rom bios from the hard disk.
If you are going to put a new one, you have to get the bios and utility software from compaq before installing your operating system.
