As far as I can tell this happened when I was converting this computer from a file server/desktop running 9 current to a freenas server. I rearranged all hard drives and removed some expansion cards (pci firewire, pci-e Sapphire) removed DVD drives and installed one CD drive. All in all I had my hands in the MB quite a bit and could have done something even though I was careful and always grounded myself. Of course, I had the power off whenever working inside the box. I will be taking the computer down in the next few days to add another drive to create a mirror. At that time I will do all that you recommended. i.e. Blow out the dust bunnies, double check all connectors, redress all cables and the run memtest. The MoBo is not new and has been in continuous use for many years. It is not inconceivable that I have a trace problem or a cold solder joint somewhere. Thanks again for your reply.
