Graphic card issue with Mac pro 8 core

[satishmoney]

Hello hi,
I have a mac pro ,8 core which i bought two months back by march 2011.As i started using it i had been experiencing some issues with the graphics card.the card which i got was a ATI radeon HD 5770.when i started using Zbrush for eg., i did get some unusual blemish on the screen.There is similar issue with the maya view port as well.I have attached an image for your reference.Any help or suggestion on this issue ?Please do help ,it would be great.

Thanks a lot,
Satish.

hi Cindori,

Thanks a lot for your replay.I do suspect the same as well.But i just want to know what are the chances for the issue to be in the software ?Are they are possiblity that the issue might be in the software?I use zbrush, maya 2011 and photoshop cs5.



Thanks ,
Satish.

If you have it in more then one software, then it's definately hardware.

hi Cindori,
As you suggested ,i called apple care.They suggested replacing graphic card.it didn work ...infact they changed it twice ,still no response.They chnaged my RAM ,still no change .Erased my hard disk n formatted it thrice ,still no change.I started problems in photoshop ,itunes ,safari.so i was frustrated and finally apple gave up and replaced the entire machine.The most frustrating part is ,the problem continues even in this new machine with itunes ,maya ,zbrush .I am worried n desperate to fix this problem. Any ideas n suggestions from u would be of great help.

Thanks a lot,

If the problem perists across different machines and different apps, move the machine to a different place (e.g. 1 km away) and check again. It may be an unsually strong interference from some broadcasting or mobile phone station. Seems to be an environmental problem.

Thanks a lot for your reply..
yea i did try the same softwares by moving the machine to service center.we tried all the test,still no solution.I am feeling very bad and let down .i have invested almost all money on it ,i dunno what to do now.i thought it might be the mnonitor issue ,so tried it with a different monitor too.Still no solution.tried booting with external OS ,stil problem occurs.
