text: i'm getting error code 19,computer is not  recognizing my keyboard.? i have uninstalled & re-installed to no avail.  this happened after i installed 512 mb more memory in my computer.  it worked fine after the install but the keybord was dead the next morning.  it is difficult to do any searches or registry fixes without a keyboard :-( go to safe start. whin you boot press the f8 button. when the curser is in the left hand corner. top of screen.and add that way.
