I did for a while a couple of weeks ago while changing the mainboard on this PC, things did not go well. I did think I'm going buy Pc's built up in future!, however all is well now & I'm happy again. :-)
The only time I thought computing was not for me was when I got my first computer. I could not make head nor tail of it and came very close to giving up. I persevered and now would not be without one. They say that there are many computers dumped up in peoples attics just because they could not get the hang of them and all for the want of a bit of perseverance.
