I just bought a 2.8 dual quad-core mac pro and a 23 inch cinema display 2 days ago and I've been having small color lines show up on my screen after running the computer for about an hour. It usual happens when im in safari or firefox. and when it does happen the computer totally freezes. Im not able to force quit or do anything except restart from the power button. This happens again after about an hour or 2 and i have to do it all over again. Any idea why this happens before i lug the computer back to the store? thanks...
I'm running mac os x 10.5.1, ATI Radeon HD 2600, 2 gig of ram
2 x 2.8 GHz Quad-Core intel Xeon
Mac OS X (10.5.1)

To rule out a display issue, you'd want to connect another display. Might be a problem with the video card. Are you getting a kernel panic, with screen messages like the ones in the following Apple Support article?

MacPro 2.66/4.0/750/G8741..+23"Cinema; 24" iMac 2.4/4.0/320; MacBook 2.2/4.0/160
Mac OS X (10.4.11)

There isnt a message thats says its a kernel panic its just a hard freeze and whatever i was doing at the moment is whats on the screen. I tried it with an older 22inch cinema display and it does the same thing.

Have you run the Apple Hardware Test? I really don't know if that tests the video card, but it for sure tests the logic board.

Dude, I am totally having the same issue. Mine happens when I shut the machine down. It will boot up and I will get the lines on my screen and then crash. I then have to reboot, sometimes 4 times before it quites happening. Any thoughts from anyone? No hardware tests, including Tech Tool finds anything wrong?
This happened in 10.4 and 10.5, as well as two monitors, so I really think it is hardware.

My new Mac Pro (2.8 2 x Quad) has also frozen a number of times since day one. The details are over on xlr8yourmac.com with others who are experiencing the same issue.
I usually only get a small spot of screen corruption around the mouse pointer - about the size of a postage stamp - when the freeze happens, but 3 times the screen (30" HC CD) has become totally corrupt with many wavy lines and artifacts running thru it. The mouse pointer stays moveable in all cases, and background processes continue although I cannot force quit or restart in any other way than hitting the power button. Has happened twice in five minutes and then not once for as many as 3 days... seems to have no rhyme or reason.
I also have one of the freezing Aluminum iMacs with the very similar Radeon 2600 Pro card; the behavior was almost identical. Apple eventually released a firmware update that fixed the issue, and I find it hard to believe they would have brought the faster XT card to market without thorough testing, but... it's beginning to seem that they have.
