[ale] OT - hardware problem

[Joe Knapka]

I'm pretty sure it's not the fan, because when I did get the machine
to boot into the BIOS, the BIOS status screen reported fan speeds in
the 3000-4000 RPM range.

I'll definitely look into the capacitor problem, though.  My soldering
skills are only fair, but this might be a good opportunity for a
Learning Experience :-)  I don't know exactly when the board was
manufactured, but it's a BioStar 6100-M9 Socket 939.

Woah.  It's capacitors.  Two of the big 3300uF ones right by the CPU
socket are cracked like eggs.  Gotta find that soldering iron and the
desolder .
