OBG,

Before loading up ole Betsy and taking that varmint for its last hike, you might consider simply removing its hard drive and getting new one and re-installing the operating system and programs that you were running from the original CD-ROM's to avoid re-contaminating the new hard drive. Before connecting the newly revitalized PC to the networks etc. make sure that it has some good protection software installed. Take the old hard drive and get it completly reformatted, in the old days you could do a low level format, now it is a bit harder. Depending upon how big the drive is and how much the replacement cost (as well as the intrinsic value of any of your precious data that may remain, you might opt to dump it, in which case destroying the hard drive physically will ensure that your data is not recovered by the less than honest folks that may come across it.
