??? do you mean format my computer? I suggest you go to the hp support site at http://welcome.hp.com/country/us/en/support.html
you can type in a question in the search box at the top of the screen or type in your model no. and then search for troubleshooting tips..however I tried typing in your model no. and it's not coming up.
When you format a drive you erase everything on it...
