Chosen Solution
Hi Guys thank you for your time, and thank you for your help I’ve been in trouble with my old (early 2008 iMac ) The problem was it was starting correctly but after it, I can’t do anything, like open an app or use the utilities, open a files…. Just the rainbow circle been loading for ages So I can just turn it off manually I’ve been trying all the reset PRAM , S , C and after discuss with you on ifixit, the best solution was to change the hard drive So now I have a new one , but after the installation with the 2 disc. it keep freezing, on the first parameters when you do the installation, freezing on my personal information after completing them and press continue, the rainbow happen again and keep charging forever… So I would like to know if I need to add more RAM or anything , or if is better for me to stop putting money on it and give it away Thank you all for your help ! I really need it ! Update (04/10/2020) Apple iMac 20-Inch “Core 2 Duo” 2.4 (Early 2008) Specs Identifiers: Early 2008 - MB323LL/A - iMac8,1 - A1224 - 2210 The Original HD was a Western Digital WD2500AAJS. 250GB TRNDA 655. 1358D And I replaced it with a Seagate HDD 3.5 SATA II. 250GB So as I check before my iMac should support it
Examine the capacitors (cans) on the power supply to see if any are swollen and/or leaking. Power supplies can partially fail. I take it you booted successfully from the optical drive. UPDATE 4/11/20 The capacitor to look at are the can looking things shown here, click on the image to blow it up: iMac Intel 20" 2.4/2.66 GHz EMC 2210 Power Supply
