John: Everything you wrote was very interesting to me! This box was shipped on 1/6/2005, according to the Dell web site. That may give me some other options. Hoping to take it in (about a 90 minute trip) to the man in Cali on the 5th or 6th of January. He spends his days fixing motherboards. He also can take a look at the PSU, which I suspect may also have issues. The city of Cali celebrates "Feria" (fair) between Xmas and New Years and a lot of places are closed or close at Noon. Thank you and Happy New Year to you and your family! Lanny
