I have an old Dell PC w/XP. I would like to keep it and use it for something if I could. I have reloaded the OS before. That was when I had a virus. However, that was a long time ago. Is the documentation anywhere of what I would need.  I reloaded a lot of Win 95 machine and had it down to a science. Complete with full documentation. Where could I find similar instructions for an 2005 XP Machine?  In other words, should I look on Dell's web site, or MSFT's web site, or perhaps some place else?  I have done it before, but that was a long time ago. A check list of what I would need would be nice.  My new PC, is great. Very fast and uses a lot less power. It no longer heats up the room it's in.
