I read the other step-by-step instructions on changing the graphic card, building a desktop, and cleaning the keyboard, etc. A very helpful site.
Now I know how to do all my hardware ugrades and maintenance on my computer! Luckily, I know where to get most of the tools and components I need, but it seems that whatever I want to do with my PC, I also need some Swedish steel wool with soap, "Svinto" brand... I'll look for it next time I go to Wal-Mart... I hope they sell Svinto in Canada.
I wonder if Docktor Nårton teaches anything else, like do-it-yourself heart surgery.... just use your handy data-grinder to cut, make sure you wear your safety surgical gloves, use medical tongs to pry things out that can be discarded, scrub organs with Svinto steel wool, put everything back and seal with tape... there, wasn't too hard, was it?
