Startup freezes on a black screen with small blue and red boxes

History

For MacBook Pro model number MA895LL/A

The blue and red boxes go diagonally across the screen. The computer will not allow me to start up in other modes or get to the boot setup menu.

I think its the graphics card, but can not find a replacement.

Any ideas?

Try an external monitor?

machead3,

Did you try a target boot to retrieve data?

machead3,

Do you have the 15 or 17" model?

Your machine has the Nvidia video chip. Hook it up to an external monitor. If the problem persists Contact Apple and get a free replacement logic board. Here's where to contact them: http://www.apple.com/support/contact/pho...

Here's the issue: http://support.apple.com/kb/TS2377

If they give you any problems go to this web site: http://www.nvidiasettlement.com/

There are no replacement GPUs

if that's what you're asking. The GPU might be shimmed, reflowed or re-balled...otherwise you'll have to replace the logic board.
