who "kicked" the box last? :) first make sure everything is seated well.
if still rebooting, take your favorite *BSD live cd and see what that
does. i don't recall what freebsd has, but trying booting the default
bsd.rd (openbsd) from the disk. you can also boot memtest86 too - or a
simple dos disk...that's some things i'd start with...

good luck.
