    The other week I got on my iMac and saw that there were green and purple dots all over my screen. I have no idea what they are from or how to get rid of them. Can anyone help me?

    Call Apple and get it fixed if you're under warranty.

    They are dead/stuck pixels incase you were wondering google how to remove stuck pixels or it could be your GPU try restarting your imac and doing PRAM and SMC resets Try creating a new account and see if they go away, use it for awhile then switch back to your old one that could help

    Can't be dead or stuck pixels because otherwise they wouldn't show up in screen shot. Sounds more like a GPU issue.

    Still, if you're under warranty, call Apple and get it fixed

    Wouldn't be surpised if the problem comes back.

    Looks really odd, is that a screenshot taken in OS X or a picture of the screen taken by a digital camera?

    Seems to me like a GPU processor or GPU memory impending fault.

    Mmmmmmm green micro dots. They were always my favorite at Dead shows! :D

    As for your screens dots I hope you are still under warranty because you need to call Apple and have it addressed - you have a GPU that is going to die soon.

    Graphics Processing Unit. Your video card. What video card do you have in your iMac.

    Multi colored dots on the screen usually mean the VRAM is overheating. Nothing you can really do about it other than contact apple and get it repaired.

    Ok so now my computer won't turn on at all. The outlet is working fine and everything is plugged in. Why is this happening?! Is taking it in my only option now?

    My instant reaction would be that the video card has completely killed the motherboard and it's refusing to power up due to physical damage, or some kind of error/power problem - which is serious, because it could be electrically unsafe in its current condition. With the issue you had, it's probably due to overheating (causing permanent damage)

    Thing is, I would have expected much worse visual distortion if it's due to video card overheat, especially since the entire desktop is composited by the video card. Which leads me to think that you should go see to an Apple Store ASAP and get them to open it up
