That sounds like a ram problem!
Perhaps one of your modules has dislodged and need to be reseated, or is failing.
1. Try reinstalling-reseating both modules, firmly pushing on each one with both thumbs then close the ejector clips.
2. Then if it still acts funny, try installing one module at a time.
If and when it happens again, note if the LED is flashing once per second or three flashes with a pause. See the [Intel iMac Startup sequence|http://docs.info.apple.com/article.html?artnum=303363] article.
The hardware tests from your [Install Disk 1|http://docs.info.apple.com/article.html?artnum=303081-en] or [TechTool Deluxe|http://www.micromat.com/index.php?option=com_content&task=view&id=199&It emid=104] can be used to test the ram.
