Lots of "faulty" capacitors were apparently produced around 2000-2001 (???), and many electronics (like motherboards) have been failing (since 2001, apparently). We had a motherboard with these bad capacitors, and FreeBSD would "just hang" on it. Eventually, the hangs got worse and worse until the hangs occurred during the BIOS bootup. Look for small amounts of light brown/wheat colored "mud/dirt" on/around the capacitors. See the pictures in this article: http://www.spectrum.ieee.org/WEBONLY/resource/feb03/ncap.html Specifically: http://www.spectrum.ieee.org/WEBONLY/resource/feb03/ncapf1.html (It's a bit hard to see, unfortunately.)
