dont know if this is where i should post this or not,  Im trying to fix a inspiron 2200 and when i turn it on it has a password screen that i cannot get passed.  When my friends son got on it the other day instead of typing in the password he hit delete and now none of the passwords work and i cannot get into the computer.  Is there anything i can do to get this fixed.  any help would be greatly appreciated!  thank you
