    I was working in photoshop last week and noticed that the mouse/wacom was acting sluggish and then all of a sudden my Cinema Display 27 went dark and never recovered. Since then I've been resetting all I can without the aid of a display and tried to reinstall osX by disc but no luck.

    I was thinking is was the Radeon HD 5770 but wanted to see what the community had to say.

    I am attaching an image of a lit red diagnostic LED if that helps.

    Thanks for any and all input on this issue.

    From looking at the photo, it seems like slot 1 of your ram has failed. Try removing it and seeing if the system boots?

    Thanks for the replies, will be checking the ram this week as I would like to max this one out. I did replace the video card with another ATI 5770 and was able to get visual again.

    Thnks again for the input.
