It's just two clicks to the XP Shutdown Article off of http://www.aumha.org/articles.htm
But my guess is that you don't realize that Microsoft doesn't install for you the drivers for your motherboard. It's not listed in your post. You also neglected the Forum Tip and didn't reveal the make/model of the machine. AMD based setups are very rough on first time OS installers. I can drop hints till you get a Macintosh, but if you don't install the motherboard driver package, then hangs will happen.
Same story about PARASITES. There are many that get "Kazaa'd" and these can't be helped. You can only wait for them to get burned multiple times.
When I'm downloading torrents from the web and want to shut down my machine it won't disconnect from the net or shut down which means I have to press reset and then shut down after restart. Tried reinstalling windows xp pro from scratch and also all drivers & software. Also tried different torrent downloaders Even changed my motherboard and various components to no avail. Any ideas?
