Well, that fixed the keyboard, as you can see from this message being typed, but the mouse is still not working. The fly-over features of the mouse work (it shows the text associated with an icon) but the mouse will not move. I then tried to uninstall the mouse PS/2 from Device Manager. Yes, it has a yellow exclamation point indicating a problem. So far so good. Upon reintroducing the mouse (and keyboard) into the system, device manager once again shows the exclamation point.
Next, removed the mouse again and installed a new and different USB mouse, which the system saw as a new piece of hardware. Nevertheless, that mouse also would not function.
My fingers are wearing out from tapping the Tab key to course through the choices on every page to which I go.
It's sad, I'm sad. Please help!!!!
