Can anyone help.

A few months ago I purchased a second-hand MACII at what I thought
was a good price (what a mug). Everything seemed to work OK except a 
few applications under multifider. This I put down to the
applications not being Multifinder compatible, since they
worked quite happily under the standard finder.

However, I recently, installed THINK C 4.0 on the machine and
tried to run the debugger (THINK C requires the multifinder).
As the debugger started up the system immediately
fell over with a system error ID=11.

My first thought was that the system was corrupted, so I 
installed a new system. This didn't work. Next I reformated
the disk and installed the system afresh. This again didn't
work.

After a long period of experimentation I found that the system 
only seemed to fall over when a BLEEP sound is made whilst 
running under multifinder.  This could be invoked by changing 
the volume level in the control panel to a non-zero value.
Also, if the sound volume was set many times in quick succession
the system did not fall over until after the last BLEEP was 
heard. Resetting the PRAM before setting the sound volume
allowed me to set the volume OK, but after re-booting the problem
reappeared.

I would like to take the machine in for repair, but here in 
England my local Apple dealer wants 90 pounds sterling (approx $150)
just to test the machine.

Has anyone any suggestions as to the cause (eg could it be the
Lithium batteries going flat, or is it something worse). Does
anyone know of any software that I can get hold of to do a
hardware check myself.
