This is a special case...
I did a hard drive replacement on this iMac about a month ago. Have not used it for about a month. Today when I try to boot it up it beeps like it has no or bad RAM. I tried new RAM sticks to no avail, still beeping like it has bad RAM.
While removing the screen to replace the HDD, the vertical sync cable came out damaged. I did my best to put it back in. Would a damaged vertical sync cable be causing this?
Is there a pattern to the beeps? Did you address the hard drive thermal issue if you changed brands of hard drives?
What are the diagnostic LEDS telling you?
