Downloading Yosemite on Macbook Pro 2011 with GPU glitch

[afmbp]

Hi,

I was wondering if its safe/ good idea to download the new Yosemite update on my Macbook Pro 2011 which has recently started to suffer from graphics card failure?

The problem is especially evident at the start up, generally my mac will shut down when asleep and when I attempt a normal startup I will get a pink screen.

I have found that this can only be resolved by attempting multiple different startups (verbose, sing user reboot, NVPRAM, SMRC...) until it switches on again to a blue/ grey scree.

Do you think I should attempt to download Yosemite? or will it only cause further problems....

It is risky because you could get stuck during the installation.

As answered in another post of yours: it doesn't matter. Failing hardware is still failing hardware no matter what software is running. You don't run any more risk of your GPU completely dying out of the blue by installing Yosemite than by keeping things as is.

I'd not try it, you'll potentially be making things worse.
