Weird chessboard like screen problem on mac pro

kocaelisporlu · Nov 7, 2012, 03:10 AM

Hi. Until now I've changed the rams and format ios but nothing changed so far.
Is there anyone faces with this problem before?

Thanks

Restart, if all fails screen got owned.

Here I guess you want a new screenshot.

----------

Changing the monitor doesn't effect anything.

OS got owned.

What mac Pro, what graphics card and version of OSX are you using? Are you still under AppleCare?

It could be the graphics card ram or it could be something that would be resolved by an OSX reinstall.

I assume you have performed an SMC and NVRAM reset? Try that before anything else.

SMC reset from Apple : http://support.apple.com/kb/HT3964?v...S&locale=en_US

NVRAM reset from Apple : http://support.apple.com/kb/HT1379

Try that before taking anything out of the machine.

video memory fails

and chess-like screen because of video memory tiling.

mac pro 3.1 xeon processor

We've tried both graphic card (ati 5870 graphic card and ati 2600xt) But we got same problem as always.

And near time we did change the ram kit also.

----------

I'm thinking it could be the motherboard the guilty. because this is the second time we are changing the ram kit and third time changing the graphic card.

Have already tried reinstalling the system?
If you hold CMD and R while booting, you should get into the recovery partition. Are you seeing the problem there as well?

If so, try another PCIe slot.

kocaelisporlu · Nov 13, 2012, 06:27 AM

Yes. I tried another slot and also I see same errors while starting up the system.

Without a picture I'm really guessing, but I'll try guessing something that hasn't already been mentioned.

Dirty keyboard? The keys pressing onto the screen while it is closed, leaving a faint 'chessboard' like pattern.

just guessing

I thought for sure it would have been the graphics card, but as you say, you've replaced it twice now. I would try a different monitor, different video cord, and different PCIe slot.

Mac Pro, not MacBook Pro.

You are not serious of course.
