Q: 27" iMac (09) is repeatedly shutting down

(or at least the display is). Clearing the PRAM and SVC did nothing, and I cannot run the AHT by restarting and holding down D... Suggestions?

Hi Dean_0h,

I have to say before you begin troubleshooting, that this will take some time to get it worked out. Take a look at the article below and start with the Isolate hardware or software as the cause of the issue section to see if you can get to the bottom of it.

OS X: When your computer spontaneously restarts or displays "Your computer restarted because of a problem."

Thank you for the reply, norm123. Unfortunately it has been rebooting while booting up, and had never given that sort of a message before. I don't seem to be able to start it in safe mode either.

Hello Technician7,

At that point, I would recommend contacting Apple for additional support. You can either call in, take it to an Authorized Service Provider or an Apple Retail Store. To get you started, take a look at the link below to get you started.
