I appreciate the help, Tim. I cleaned out the dust, removed the cpu, cleaned it and the socket, then re-applied thermal paste. That brought the temps down from mid 50s to a range between 37 and 40 C. It seems to be firefox or flash player causing the problem. I have Win xp 64-bit, and Mozilla doesn't have a version of firefox specifically for that OS. IE seems to work fine.
I would have responded sooner, but I couldn't remember where I had posted this cry for help. I really do appreciate your response.
Hi Tim Quite right. Plainly said. Welcome to this world of rationality and peace, where pure common sense is enough to lead to the open freethinking wisdom common to non-believers. We invite you to join the busy group "ORIGINS: Universe, Astronomy, Life, Earth, Humans, Religion, Gods, Atheism, Evolution, Darwin..." with 700 discussion topics and 3600+ members. http://www.atheistnexus.org/group/originsuniverselifehumankindanddarwin Terry
After you've searched for topics of interest in "Groups" above and in the "Forums", don't forget to look at recent activity which hides along the right margin of the page all the way at the bottom.
On a personal note, I've developed an animated gif technique, sort of “pull quote marries slideshow”. Samples are scattered across various groups, but you can find them easily by going to my twitter account. Each tweet has a link (after the description and before the hashtags) to a visually rich example here at Atheist Nexus. If you like them, please follow me
