Stumpy has helped me a great deal, very in the know; but Hoodlum how did you learn how to do all the things your talking about? It boggles my mind what some of you can do with a computer; do you all have super high IQ's? rt...
It's really about just diving in and learning.
I have never been computer tech savvy, but last year, I decided to start being so. I built my first PC from the ground up, and I have since maintained it. There was only one time that I had to take it someplace to get fixed, and that's because it was REALLY involved and I had multiple issues going on, masking where the root of the problems were coming from. I worked with the tech regularly so that I knew exactly what he did and how to trouble shoot it. Now I have all kinds of cool diagnostic stuff on my PC, and this particular one I don't do anything except for gaming on. I use a trashy laptop for everything else.
There are lots of great forums for stuff like this too, just like the BBing community, there is a computer community.
