I took it to the Apple store and they replaced the hard drive in 2015. It still didn’t work when I got it home. It would strike the familiar chord, the little apple appeared, the screen had wide white and yellow stripes. When the spinner stopped, the screen was white with little yellow squares, the apple in the center was grey with little purple squares. (Psychedelic, huh.) I turned it off and sort of forgot about it, since I had no more money to fiddle with it. It just sat, covered, until today. I must do something with it (small house, new roommate). I plugged it in today, turned it on, and the exact same thing happened. Any advice is appreciated (not about procrastination - heard it all). Thank you for any advice.

Sounds like an issue with the GPU. Not too common on the 2010 iMacs compared to the 2011, but how you've explained it -- sounds like it is a GPU issue.
