Heyo, I have a quandary: At work today, I was using Photoshop CS6 editing an image and got the beach ball - which is not surprising as this happens often enough in PS - but it went on for a minute or two, way longer than usual, and then the screen went gray. It's an early 2011 MBP that shipped with 10.6 and I did a soft upgrade to Mavericks a couple months ago. It's been glitchy since then but nothing I can't stand and no major problems at all. I powered down using the Press-Hold salute and now it won't power up AT ALL. If I put my ear to the casing I hear the drive engage, but it won't do anything else. Screen won't even light up. Also, I tried plugging in my 10.6 boot drive and that doesn't do anything either. Cliffs: - Screen went gray whilst using Photoshop - Manually powered down - Won't boot - HD seems to engage - Bootable drive won't work either Any help would be absolutely fantastic. Thanks in advance! As a token of my appreciation I will gift the most helpful reply with a WHOLE U2 ALBUM through iTunes!!! EDIT So after some more intensive troubleshooting, I can get it screen up, but it's pink/red stripes, which led me to search and find this thread: http://forums.macrumors.com/showthread.php?t=1675508... welp, there goes my hopes of selling it on craigslist! It's in brand new cosmetic condition and I've taken fantastic care of it. Ah well. Not spending >$700 on a repair when it's not uncommon to happen again and I can get a Air for just a bit more. $H1TE!
