I've had problems such as you describe when the Transwarp overheats. 
That problem can be checked by taking the top off the cpu and running
the comptuer for a couple of hours.  If it works okay then you need to
figure out how to cool the inside of the GS with the top on or run it
with the top off.

There are two ways to disable the Transwarp.   The Transwarp utility
is found in the control panel and accessed by pressing on the 3 keys
[control, open Apple, esc] at the same time.  The Transwarp utility
will be visible when you do that.  Double click to open it.  You can
try disabling the transwarp by changing the speed to 1 mhz.  There is
also a self test you can run.  There is a 14 mhz chip available from
Western Design Center and oscillators elsewhere to replace the
oscillator.

If you are having problems with the transwarp you may have to pull the
card and cable as well as the piece on the end of the cable that fits
in the cpu slot.  You will need to put that origional cpu chip in that
slot to make the computer work.

The GS will usually work with a SCSI IOMEGA ZIP drive.  You can get
the 250mb size and back up to those disks.   If the files are small
enough he could save to 3.5" floppies.  It would be much easier to
recover his files.  The machines have lasted a long time, so he may
need newer ones to continue using them.
