Why is my iMac randomly shutting down?
imac early 2009 os x 10.7.5 previous shutdown -128
I've done SMC reset several times. Checked temp. Problem is intermittent which is to say, I can't create the conditions for it to shutdown. Always get the same message Previous Shutdown -128. Can't find any code list; so I don't know what -128 means. What could be wrong?
Is this a good question?

Can you give us the exact error message besides the code. Sometimes its an app Vs the OS that is to blame here.

Also can you give us the last three digits of your serial number so we can correctly identify your system.
