I have been into computing for about thirteen years now (since I was seven when I started). And that's not just playing games. I am constantly fiddling with applications/drivers/batch files/hardware etc. most of the time causing myself problems to see if I can repair them myself. I am frequently requested by all my PC owning friends and colleagues to fix or install things onto their machines - I haven't permanently broke anything yet! My PC is built up from scratch by myself (I also assembled my mates PCs).
