My early 2011 15" MBP has developed the same problem. No warning. Two days ago, the screen went blank (it went dark grey as it played a Netflix streaming video, not at fullscreen), and it wouldn't restart: the Apple logo appeared as normal, but then it would freeze on a grey screen. Just like most of you.
Initially, resetting PRAM made no difference, but after a number of tries, I got it to start. After about a minute, the screen started to flicker and shift erratically (mostly horizontal shift), and then the computer froze, displaying a blue screen w/thin vertical stripes. I wasn't pushing the video card; I was only surfing the net, looking for information on the problem.
Restarting now is hit-or-miss. I usually have to try a few times, and when it does start, I can't do much of anything anything that really uses the video card. If I even reposition a window, the screen goes glitchy. When it crashes, it's usually the same blue screen w/vertical stripes, or a crazy blocky diagonal pattern. I can't work with images, which is what I do for a living.
After spending some time looking through these threads and other available information, I'm amazed to discover that this is a such a widespread and clear problem. It's ridiculous that Apple isn't fixing this; it's 1) obviously a known issue, and 2) obviously a manufacturing issue.
I shouldn't have to be worrying about replacing my computer. Neither should you.
None of us should have to be dealing with it, and it's not okay that Apple isn't rectifying it. 2 1/2 years simply isn't a reasonable lifespan for any computer, let alone a MacBook Pro, and imaging and video failing can't be something to worry about on a machine that people do professional imaging work on. ... What does the "Pro" stand for?
If Apple's MacBook Pros can't handle imaging any longer, the professional community needs to start looking elsewhere, and if Apple can't handle making right on a manufacturing problem that's clearly theirs to make right, customers need to start looking elswhere. I'm a graphic designer, and I've used Macs for over 25 years. I stuck with Apple through their hard times, and I'm very sorry to see this happening. I'm not really bothered that they had a manufacturing problem; that happens. I wouldn't hold that against them unless it continued to happen. But them not making it right is something else altogether.
I'm sorry to hear about all of you folks who have been trying to deal with it for months now. I hope Apple doesn't continue to ignore it, and that they step up soon.

I'll be bringing it into the Apple store so they can have a look and so that it's on record, but it doesn't take much to know what the problem is.

Okay, can anyone help me with gfxCardStaus... I can't switch to "integrated only" without the computer immediately freezing and crashing (turns to the crazy zig-zag pattern).
I can't believe this is happening.
