Apple's 2011 MacBook Pro lineup suffering from sporadic GPU failures
Owners of early-2011 15-inch and 17-inch MacBook Pros are reporting issues with the discrete AMD graphics processors in their notebooks, which in some cases results in the failure of the component, leaving an expensive logic board replacement as the only remedy.
The problem, as highlighted by multiple threads on Apple's Support Communities forum, first presents itself as a graphical glitch -- or, in more serious cases, complete system lockup -- when an affected MacBook Pro switches from the integrated Intel graphics chip to the discrete AMD graphics processing unit, or GPU. Reports of the issue first cropped up in February, but have become more frequent over the past month.
In 2010, Apple introduced the automatic graphics switching system, which dynamically shifts the processing load between the integrated chip and the discrete GPU based on what the user is doing. Owners of MacBook Pros built prior to 2010 have to manually select the more powerful GPU from OS X Settings, which forces the operating system to restart.
Users of affected machines report that display discoloration, banding, and image distortion are the most common visible symptoms, but many say that their computers suddenly freeze without any of the graphical warning signs. Rebooting --?even several times in succession --?rarely fixes the problem, and some have even tried to remedy the situation by forcing their laptop to use the integrated chip exclusively with only moderate degrees of success.
Data compiled from several Apple Support Communities threads by forum user "saramwrap" suggests that the majority of affected users are using early-2011 MacBook Pros with the AMD Radeon 6750M GPU, though failures are not limited to that chip. Those whose notebooks contain Radeon 6490M, 6750M, and 6970M GPUs are also experiencing the problem.
Apple has yet to address the fairly widespread issue, with many users reporting that the only repair option given to those without AppleCare coverage is a complete logic board replacement at a cost of $500 or more.
Apple's popular laptop line ran into similar troubles soon after its early 2011 hardware refresh, coming to light in another Apple support forum thread that now stretches more than 140 pages with over 2,000 replies. ArsTechnica reported at the time that Apple was aware of the issue and specifically targeted the problem with a special build of the OS X 10.6.7 update.

I had this issue 2 months ago. It started with some graphical glitches and it worsen by the week. In the end it would freeze minutes after a reboot.
Took to an Apple Store, PRAM reset got me an extra week until all the problems returned. Had to fork over £400 to get the motherboard replaced
Did this still occur when you switched between to the iGPU over the dGPU?
I thought warranties for items were 2 full years in the UK for electronics.
That proves it's form over function and that a $400 notebook is better. /s
Speaking as an IT technician that has to fix those $400 notebooks you're full of crap.
Failure rate of MacBook Pros are CONSIDERABLY less than the failure rate of a $400 laptop.
There's still the elephant in the room though. That $400 notebook is still running a crap OS... even with Linux on it (Yes I damn well went there).
Did this still occur when you switched between to the iGPU over the dGPU?
Yes. After about 1 1/2 week on iGPU the problem started to show up again. gfxCardStatus didn't help much unfortunately.
Well that's one way to promote Apple Care
Is /s really an unknown concept for someone1) on the internet, 2) on an internet forum, 3) who has been a member of this forum for over 1.5 years?
Hmm. Considering it's happening across multiple dGPUs and the iGPU this seems different from other GPU issues that have cropped up over the years. I hope you get your money back for the new MoBo when this is all said and done.
There have been plenty of issues with Nvidia components. Here's one major issue involving Macs: http://support.apple.com/kb/TS2377
I have a mid-2012 15" MacBook Pro. "Graphics NVIDIA GeForce GT 650M 1024 MB"

Hope so too man. It was very weird and I thought of *gasp* reformat. But working on IT I tried to isolate the issues and in the end what happens is the smallest change in GPU, sometimes unnoticeable, crashed the whole laptop.
The system.log messages were pretty weird and the Apple Quick Hardware Diagnostic that the Genius runs shows no problem at all.
Well that's one way to promote Apple Care
Or perhaps Apple to get into the GPU business. I wonder if those Ax graphics guys can help out
Which is a huge point if you had to ever run the latest versions of Windows. Linux isn't that bad if you GUI expectations are low and you can deal with the limited app environment
AppleCare for a MBP is $349, it still isn't a good deal. In fact it is a terrible deal considering it only provide 3 years of warranty protection.
I had this on a 17" way back... I posted in the Apple forums about my experience and was contacted directly by Apple. They replaced my older model with the brand newest 17" -that happened to be the last of its kind
Actually NVidia had a huge problems in MBPs a few years ago. I wouldn't be surprised to find that the move to AMD was the result of that issue. In NVidias case it was a solder joint failure problem. We don't know what is up with the AMD failures but at this point they don't appear to be even close to what owners of those NVidia powered machine experienced.
It will be interesting to see what the root cause is with this stuff. it could be an assembly problem, an AMD design problem or a problem with TSMC processes.
Funny isn't it?
It will be interesting to see if they can come up with a common failure mode like the NVidia chips had. Frankly I don't think at this point they really know, however this seems to cover a wider array of chips so mostly likely there is more than one thing going on here.
