Having problems with your HP Pavilion dv4000 Notebook ?

When I touch my keyboard my computer freezes

\015 Two days ago I started the laptop and when I attempted to enter a web address the computer froze. After many trials I came to find out that the mouse touch-pad and buttons would work without fault but any key on the key board had fatal consequences. I also realized that the computer continued to process programs even though the keyboard failed to respond to the second keystroke.I've run the antivirus programs and attempted to restore the registry but nothing has worked. In fact when I attempted to restore to an earlier date the system informed me that it could not process the request. So I'm Stuck.I even thought of trying to find the default registry of this laptop and installing, but I haven't been able to find a copy on line. \015
