if you have a usb keyboard sometimes the bios will not recognize it. do you have a ps/2 keyboard you can try temporarily? there may be a setting in the bios to always use usb keyboard.
Thanks again. This did work. I'm back online with the pc (with the ps/2 keyboard). Should I now go into the bios to look for the setting to again accept a usb keyboard? Your advice was a lifesaver!
