I have a compaq workstation which was donated to a charity I help. It is a nice machine and I am trying to set it up as a standalone machine. However it will not power up. They actually donated 4 and three are great they have fast scsi in them with which I have limited knowledge. This one the HD was disconnected when we received it. Fans run and hard drive light comes on then goes amber but no beeps or monitor activity. I connected the HD, same symptoms. I disconnected the scsi totally hoping to throw it into bios. Same symptoms except the HD light is continually red. I need any suggestions you may have.
