Sigh. My MacBook (my first Mac ever, period) was bought new in October '09. I opted out of AppleCare, so nothing is under warranty any more. In the past three or four days, I've noticed that occasionally photos are looking like negatives, they have strange columns, weird little blocks of color, etc. I thought it was a browser issue, but it's happened on Chrome and Firefox (however, if a certain picture is looking strange in one browser, when I past the url into a different browser, it's fine). Here are some examples that I've grabbed today: I'm not going to pretend that I have a ton of knowledge in this area, but Google is indicating that it could be a logic board issue. However, my IT brother-in-law thinks that because it's not every image, it's more likely a corrupted driver. However, he's a PC guy so he's just taking a guess. For what it's worth, I've done a PRAM reset with no results. Has anyone encountered this? I'm just sick at the thought that I'm going to have to buy for a new logic board. Ugh.
