Parents have one laptop, which is 6 or 7 years old,. and my dad keeps bitching about how slow it is. I'm not touching it because if I do, it's speed suddenly is my fault. Software they use is only firefox and Office. Knowledge of my mom is like nothing,. she blames the laptop when internet is slow. Knowledge of my dad is better, but he still wont admit re-installing windows would make his laptop faster.
