iMac just shuts down?
My 1.8 GHz Imac just shuts down when I am working. I am running Firefox 3.6.8, Quickbooks Pro 6.0 and Appleworks. Working between the applications. I recently upgraded the memory to 2 GB DDR SDRAM and upgraded the Operating software to OS 10.5.8. Before installation of upgrades I had no problems. Any suggestions on how to fix the problem? Another note: my Quickbooks file suffered a fatal error an cannot be used since this started happening. :-( HELP!!!!
Is this a good question?
