It mostly started for me with a "dead" family Vista computer that had been sitting in the basement for months. I say mostly because I was always somewhat into technology, but not a lot compared to now. It had randomly stopped working one day when someone turned it on, so I was curious to know what would happen if I tried hooking it up again. The thing actually worked that time, so my parents let me keep it, and it became my first PC.
(I couldn't find another thread like this, so If there is one let me know.)
