Hi,

I am new to this forum but not to Macs have been using a :apple: since 2007.

A few days ago an issue started where the image of the previous application freezes on the screen and/or black boxes appear around an application this is happening at random times.


I am running Snow leopard (10.6.2), have a 120gb harddrive and 1.5 gb ram.On a macbook 4.1.

I have done a permission repair and verified the Harddrive successfully as well as the software is up to date.I also reset the PMU.
I have done a hardware test that run successfully which makes me think it is my graphics card?
I read suggestions about voiceover being turned on but this is not the case either.

Can you please help me:confused:!

Cheers,

maril1111

I don't get why no one is helping!I am disappointed.
I have been following this forum for quite a while before I registered

Did I do something wrong or has no one experienced this problem before?

newbies opinion here, but i'd say it is your graphics card, and seeing that it's intel gma, it could mean a new logic board since the graphics are built into the logic board, i might be wrong though.

Give it some time, its only been a couple of hours. Its easily possible those who will know what the issue is havent logged in yet today.

It looks like a graphic card issue to me, but I'm no authority on that.

Possibly more than your computer is worth. The logic board contains most of the guts of your computer, including processor and graphics card.

Bennieboy: Unfortunately, all Mac laptops, even those with discrete rather than integrated graphics, have the graphics chips on the logic board.

I think this has been discussed before. It is not a GPU issue but a driver issue. Because if it was a graphics card problem it would not show up on the screen shots. Do you sometimes use an external screen on your Macbook?

Yes it would. Display and display cable problems wouldn't show in a screenshot, but most graphics card problems would.

Apple will replace the logic board under warranty, but they won't give you a new computer unless yours is experiencing chronic problems.

What makes you think that?

I doubt if it'll affect your GPU one way or another. You'll probably still have the same problem on Leopard.

You can't install Tiger on that computer. It was never released as a retail copy, only on restore disks with early Intel Macs. The MacBook 4,1 came with Leopard, did it not?

Same problem

Hi, I posted the same problem a couple of days ago:
http://forums.macrumors.com/showthread.php?t=876075

and I'm still not sure what to do. In response to Intell, I do regularly use my macbook with an external display. However two days ago I completely erased my hard drive and reinstalled Snow Leopard from scratch without connecting to my external display at all and the black boxes are back. :confused:

I just came back from the Apple store and it was indeed a hardware issue. They said they need to replace the entire logic board. Since it's out of warranty I am paying $280 + tax for the replacement. They will ship my mac back within a week. On the plus side they said that if they find anything else needs replacing, such as the optical drive or hard drive, they'll replace it for free.

Ok thanks, do you think the screenshots will be evidence enough because I accidentally deleted a boot file:( and now I would have to reinstall
