Use almost any of the guides to get the frame off, this one will do: iMac Intel 21.5" EMC 2428 Power Supply Replacement
Open it up and observe the LED diagnostic lights to the right of the RAM slots and tell us what you find.

haz17, what are the last three digits of your computers serial number? that will help us to properly identify your computer. Did anything happen to it or did it just stop working? Any history you can give us will be helpful.

Serial no w8026qgddas...my imac had no problems before this, just a month before I find it hard to press the power on. Press power on many times and for 5-10 second only it worked until yesterday no responsed at all!
