#577236 - 06/15/12 05:20 AM Mac Pro Video Card Dead?
Biggerfoot I invented modding! Registered: 10/10/02 Posts: 4115	I have a 2008 (Early) Mac Pro with a Nvidia GeForce 8800GT 512mb card. It will no longer boot as it will freeze have way through...same in safe mode. I can boot into single user mode but not the with the CD. However, before this happened, the screen flash quite a bit with lots of blue artifacts and sometimes, half the screen would go white. It then froze forcing the reboot. I did reseat the card and it boot fine but did it again in a few hours. I tried a different slot with no luck. I did have a kernal panic about a month ago and the code was for Nvidia. Is there a way I can test the card or something before I spend the $$$$$ for another card?

From what you've said it sure sounds like the problem. Check eBay. _________________________ AppleCentral Trivia MM-MCF Trivia Call the Doctor

I saw one on ebay for just a few bucks less but it's used, not worth it IMO, go for the new. The 8800 is the same price so I'd go for the 5770. _________________________ AppleCentral Trivia MM-MCF Trivia Call the Doctor

With my iPad, I have not used my PowerBook (yes a G4) in ages...I think it took me an hour to figure out where I stored it! However, it fired right up and at least I have a back-up at home until I am running again.

The entire screen will be filled with them and also flash...kind of like when Tech Tool does its video RAM test

Biggerfoot I invented modding! Registered: 10/10/02 Posts: 4115	Well, after an hour of run time, it appears the new Apple ATI Radeon 5770 1 GB ZML MC742ZM/A video card fixed the problem. With my 30 Cinema display, I can really tell a big difference between the new card and the old Nvidia GeForce 8800GT 512mb card. From the way video and EyeTV works now, I am guessing the card was failing for a long time...EyeTV used to crash a lot but is working find now.
