That's where it all started for me and I was always on the computer whenever I could until my dad got fed up with me installing games and uninstalling his stuff so he password locked it in the BIOS.
So I had to figure out how to bypass the BIOS password which I eventually did by just guessing the password. Now I could play games and mess around on the computer whenever he wasn't at home but I had to hide all my games so that he didn't realize that I was using the computer whenever he wasn't at home. Eventually he did realize that so he changed the password and uninstalled all my games so once again I had to guess the password and this time I put my own BIOS password on it and all hell broke loose.
And that's where the hacker mentality started and sooner than later my dad bought a new computer and gave the old one to me.
Good times.
