I have 2 SSD Hard Drives in this mac. One is getting pretty full. I repaired it all really cleanly and it's worked fine for a long time since then. I'm starting to get graphical glitches as well as the iMac will sometimes run for a while then randomly turn to a Grey screen and then restart and sometimes it has a hard time when it does the reboot. My cursor also turns into a vertical line of dots and the screen once in a while when turning on turns like the pictures below. Is my solid state or OS corrupted? Should I pull it apart or is it the Logic bored and power supply in it that it dying. I have seen this same thing happen in the past to a old school macbook pro the really large ones. I'm sad today.
