To resolve this dilemma, I sought a local computer 'expert' to contemplate my problem, but he could not produce a solution.

XP SP2: FAQs from our Readers, Part 2

XP SP2 Frequently Asked Questions: Continued from Part 1 ... Q: " I already have Norton Internet Security installed and running.

To Upgrade Windows -- The Pros and Cons

A few weeks ago, I was called to do an upgrade on an older, Pentium 200 (P200) MHz computer. The P200 was equipped with an old-style scanner that used a special interface.
