OK, Sam, this is "The rest of the story". I got tired of walking over to our plant to work on the computer so I had the guy unplug and bring it over to my office. He didn't bring the perif's (keyboard,mouse,etc) so I took a power cable out of the cabinet and plugged it in, turned it on, WITHOUT hooking up any of the perif's. NO annoying voice. So I ASSUMED it was the power cable. However, when he took it back over to the plant and plugged everything back in the annoying voice came back so...we unplugged all perif's and plugged one in, booted the computer, no voice. Plugged the next one in, booted, no voice. We continued until all were plugged in and we got no voice. It's worked fine ever since. Go Figure.
