Just like the same symptoms on a PC. Try removing one RAM chip at a time or if only one chip is installed, then try known good RAM.

Thanks for your quick response anonymous mactech the iMac is booting normally now with both sticks of RAM inserted. Is there a utility that you could recommend to test the RAM?

Not something I normally use since I have access to the Apple Service diagnostics, but you should be able to run Memtest86+.

Doesn't this model have diagnostic LED's right smack dab in the center of the board?

No. That'd be the G5 models before it.


As far as TechTool, I use it...it was worth $99....but it sometimes doesn't work well. For instance, sometimes rather than fail a hard drive, it will just stop the test without giving you a result... That's likely just a bug in the version I have, but otherwise it's fine.

Thanks for the info i think we will invest in it
