I doubt very much that the boards are overheating, although it wouldn't
hurt to reseat them in case the heat expands a slot and causes a
bad connection between a card and the motherboard.  My suspicion is
that it has been a LONG time since she did any disk optimizing, and
over time the heads in the disk have drifted so that when the disk
has run for a while the slight expansion in the disk causes the heads
to misalign with the sectors.

Have her back up the files onto floppies with copy or xcopy, then 
low level format the disk and reinstall the operating system, then
put the files back on.  By using the "copy" or "xcopy" command, the
files will then be written back on the disk in contiguous sectors
and therefore her hard drive will be automatically optimized.
