MBP Aug 2011 flickering, garbage display resulting in a crash

Hi all,

I have a Aug 2011 Macbook Pro 2 ghz, intel core i7, 4gb ram running on Mac OS X 10.7.3.[Amd Radeon graphics]

I rarely turn off my MBP, rather I simpy close the lid and frequently use lid wake. It had been working fine till recently, when I opened the lid and after a few minutes, there was flickering and garbage display, resulting in a crash, where there was a prompt to restart the computer. And eversince then, things havent been the same😢

Now, it crashes abruptly on waking it up i.e post-hibernation. Especially when there is a use of high end graphics like Gaming or HD viewing. The screen flickers, followed by a garbage display, ultimately leading to a frozen screen and the prompt for restarting the computer.😟

Yesterday it didnt even prompt to shutdown, it simply crashed and froze😢

I have tried PRAM, SMC , NVRAM resets, but the problem persists.

PLEASE ADVICE

MacBook Pro, Mac OS X (10.7.3)

The startup disk may need repairing ...

Launch Disk Utility located in HD > Applications > Utillities

Select the startup disk on the left then select the First Aid tab.

Click: Verify Disk (not Verify Disk Permissions)

If DU reports errors, restart your Mac while holding down the Command + R keys. From there you should be able to acces the built in utilities in OS X Recovery to repair the startup disk.

See this thread -> https://discussions.apple.com/thread/4766577?tstart=30 - a lot of people are having the same problem.

Just out of curiousityl, do you have a Early 2010 model or a Late 2011 model?

Thanks for the reply. I checked as per your instructions however, DU reports the startup disk to be fine.

And I dont think its related to the startup disk as startp is fine, the graphics flicker.

Even now while, minimizing a window, the screen appeared to be a bit pixellated.

Thanks though

Thanks Clinton. I suppose mine is late 2011. Its almost the same configuration as mentioned in the forum that you directed me to, only mine has 4gb ram and runs on OS X 10.7.3

If I were you, I would add your experiences in the above thread. What people have done to 'fix' the problem runs the gamut... but be sure to add your problems to the list and seeing if any of the 'fixes' there are something that you'd like to try.

Good luck,

Clinton

I'm now running the Software Update which was long overdue, hoping that something comes out of this.

BTW, how do you switch from discrete graphic card to integrated graphic card. Pardon my knowledge, I'm learning new things at this stage.

Okay.. I tried resetting the NVRAM, PRAM, SMC et al.

But it didnt work out.

Next, I updated my OS X version from 10.7.3 to 10.7.5. And it resolved my problem for a day.

However the issue has surged back again. Distortions and garbage display, requiring a reboot. Then the screen stays normal for a bit and on opening any application, it goes garbage and distortions appear.

Any ideas?

Funny thing I noticed just now..I rebooted my MBP and I pressed Command+R and the Recovery Options window opens up ALL IN ITS CLEAR VIEW. NO FLICKERING NO BLUE TINT. ITS ALL CLEAR

Wonder whats causing the issue then....
