Hi,
I have a 1.8GGZ Intel iMac that is exhibiting strange behavior and I don't know what could be the culprit:
• It has started up by itself a couple of times (nothing set in the system preferences/energy saver/schedule
• It loses the correct time every once in a while
• and yesterday the screen went black when I was using iPhoto and I had to do a hard restart to get the screen back on
Any ideas?
Thanks/
I don't know these specific problems for this specific machine, but since you asked for any ideas... I had similar clock errors with previous machines, a G3 iMac and a G4 PowerBook. Usually this is caused by the machine not being plugged in for awhile, or a semi faulty connection to the PRAM battery. In both cases, that battery loses charge, or has it's charge get too low. The other two problems generate suspicions in me, but I can't give definitive answers.
The things I would strongly suggest are the basics. Back up all your files. Do a clean install of the OS and all updates.
Thanks, I know about the clock issues with a dying pram battery. I hope I am that lucky that is the problem but with it starting a few times by itself and the screen issue it doesn't sound like a battery. Can anybody tell me wrong? Thanks.
anyone? please...
Have you tried to reset the PRAM or the PMU?
Yes that was the first thing I did.
