I purchase this hp notebook PC,G72-C55DX in Feb2011, lately I'm having this problem: everytime certain keys on the keyboard are used "n" b" c" g" mostly, this window opens up:WINDOWS HELP AND SUPPORT.and a blue ? appears on the task bar.it is also happening when I turn the "caps lock'on or off. Also the only way I can make a C is whenI use the caps lock I cannot do it by just the shift key.
I thank you for your help, as it is getting to br very fustrating.
