Re-seating all the chips on your machine will, in my opinion and experience,
clear up about 80% of all mysterious, un-repeatable, unpredictable hardware
errors.  Back in the days of my //e, I was having wierd things happen at
strange times, and simply removing the lid and pressing down on each chip
(strange crunchy sounds were heard) cleared up the problem forever.

A similar problem on a friend's GS was cleared up the same way.

Just ground yourself and re-seat the chips.  Heat changes from turning your
machine on and off (especially leaving it on 20 hours and off 4) will cause
these types of problems.  You'd probably be better off leaving the machine
on 24 hours a day.  My //e was on 24 hours a day for 2 years straight with 
only that one incident, and my GS has been on for about 3.5 years straight
(aside from commuting to/from school) without any problems (why?  running a
bbs and then my GS battery died)...  anyway
