HELP Mac keeps shutting down


Ewen Cameron

I have a quicksilver 733 and have recently added a Giga Designs 1.47mhz upgrade hoping that it might solve my problem, but it hasn't.

Every so often the Mac just switches itself off for no apparent reason, I thought it might have been overheating and that changing the CPU might help, but I think it must be something else causing the problem.

Anyone have any ideas please?
