Resolved Scrambled graphics/artifacts on startup screen MBA 11" early 2014

[0387274]

Hai.

Everytime I boot my MBA 11" (early 2014), I get this scrambled grey screen for about 2 seconds. It boots up normally after that and no other problem persists. I bought this laptop about a month ago and it has been under heavy use ever since.

I'm on Mavericks 10.9.5 (downgraded from Yosemite some time ago)

Is my GPU failing or something?

EDIT: Reinstalling the OS from the Recovery partition fixed it.

Something might be wrong but I doubt it's the GPU. That's a part of the Intel CPU and I don't know that I've ever heard of an Intel CPU failing.

But if it's a problem that happens for 2 seconds during a period where it makes no practical difference, I wouldn't worry about it.

I had this on an earlier MBPro. It eventually became a larger hardware problem that had to be a paid repair. I would have them run a diagnostic while you have warranty options.

100% hardware. Logic board needs replacing. Take it to an Apple store, show them the pic.

EDIT: well, turns out it was software. Shows what I know :O

I'll have Apple call me tomorrow regarding this issue. I think I'll try doing a clean install first before taking this anywhere...

God damn it!

Had a similar issue on rMBP 13

Hi,

Does it happen every time you start up? I had a similar pattern of distortion intermittently when booting my 2013 rMBP 13, but resetting the PRAM would reproduce it every time.

I took it in to Apple and they ran a hardware diagnostic that came back clear. They said it could be due to a bad OS image, and on reinstalling Mavericks it sorted it out; even when resetting PRAM it wouldn't reproduce it.

The weird thing is, I returned my first rMBP for this issue, and the replacement did exactly the same thing. Before I took it in to Apple, I tried doing a clean install of Mavericks (downloaded fresh from Apple) and it still did it. I wonder whether there was a bad distribution of Mavericks doing the rounds..? Would that be possible?

Anyway, I'd be interested to hear what they do. I haven't had any further issues with mine, even after upgrading to Yosemite.

Kind regards,

Stu

Yes, it does happen every time. I'm doing a fresh install now, let's see if that does the trick.

EDIT: BAAMMM! Reinstalling the OS did it. I think I had acquired a bad OS image when I downgraded from Yosemite. Thanks guise!
