I got my dual G5 and thursday and have been noticing a problem with the video. The screen becomes distorted and random times and teh only way to fix it is to put it to sleep or reboot. My G5 has a 9800 pro card, and 2 gb of ram (one gig apple ram, one gig crucial).

My G5 is running the Mac OS X 10.2.7 which shipped with the G5.

Here is a screenshot:

who knows, but if he can take a screenshot, it seems like the problem would be either in the graphics card/driver or elsewhere in the graphics system. (ie, not a physical problem with the monitor or its connections).

It is a 20" Cinema Display. But yeah I agree with docman. Since the problem is showing up in the screenshot it can't be a problem with the monitor. I first thought it could be a loose cable.

I agree it's a bad video card.
Had a similar problem with a video card in a Blue and White G3, same types of patterns.

I had a similar problem with a TiBook that was corrected with an OS update, but it seemed to show that pattern only in the DVD player. But yeah, take it back.

I just got off the phone with the apple tech suport people, and after running the Apple Hardware test that comes on the G5 system softeware cd it seems that there is a problem with the logic board. The exact error said
"2Fan/4/8: Backside For Fan"

Well this isn't cool since now I have to take my G5 into a service center to have it repaired after having it for only 5 days.

Actually, I think "2Fan/4/8: Backside For Fan" is an erronious error and you can ignore it. See here:

Thanks for the info. I tried running the hardware test over again and this time it passed the logic board test. I guess that erronious fan error doesn't happen all the time. This time all the tests passed except the last one which was the video card test. I called Apple back to report my new findings and see if they would send me a replacement video card since I didn't want to have to leave my new G5 at a Service Provider for who knows how long. I wouldn't send me a card, but this time they said since I purchased the AppleCare plan for my computer they could send out a repair person to my apartment to replace my video card. The dispatch person I spoke with to setup the repair actually had internet access (unlike the regular tech support people) and was able to see my screenshots and verify it was definately a failed video card.

Now I have to wait for them to receive a 9800 pro and come out and replace it, but at least I will be able to limp along with my current card as I wait. Only 5 days and the extended warrenty is paying off.

Stupid question here, but uh...you need an extended warranty to cover a bad video card after only having owned the computer for 5 days???

Disregard prior post, in second reading noticed the difference to be the on-site repairman. Also understanding from numerous posts, the infrequency of this issue overall. Sorry, I'm getting angsty as mine was supposed to be here Monday and I'll be lucky if it's here by next Monday.

The fan error is incorrect. Ignore that.

Just to follow up, the Apple (well contracted by Apple) repair person stopped by and replaced my graphics card and my machines seems to be running fine. Since my problems where intermittent only time will tell if the problem is actually solved or is a flaw in the design. Since my I seem to have been the only one with thsi problem hopefully it was just a bad card. The repair person indicated that the problem may been from the card overheating which is a bit concerning seeing as the G5 has so many fans and an additional fan on the Radeon 9800 Pro itself.
