imac turns off and freezes
Hi,
I have an iMac mid 2007 (20inch) and I updated from 10.5.8 to 10.6.8 and added 2GB of ram the other day and ever since it keeps freezing and or turning itself off. I have run verify and permissions on Disk Utility and this comes back OK! I accept the computer is 5 years old but last week it was spot on and now its not.
Any suggestions?
Thanks
