I’m not sure whether this is the right forum. But my wife’s laptop opens with the message “operating system not found.” If left off for a while I can sometimes get it to boot to Windows 2000 Professional. But then, unexpectedly, it will blue screen with “physical memory being dumped” and proceed through a slow checking of the hard drive. The laptop is old and I wonder whether the hard drive is at the end of its days. But finances force me to keep it going as long as I can?
