I need some help. I am using photoshop CS5 design premium. My OS is 10.6.4. These are the specs for my mac pro.
Model Identifier: MacPro3,1
Processor Name: Quad-Core Intel Xeon
Processor Speed: 3.2 GHz
Number Of Processors: 2
Total Number Of Cores: 8
L2 Cache (per processor): 12 MB
Memory: 16 GB
Bus Speed: 1.6 GHz
Boot ROM Version: MP31.006C.B05
SMC Version (system): 1.25f4
Hardware UUID: 0613ACB3-FECF-5AE8-9CBA-353B667E52A0
The video card is NVIDIA GeForce 8800 GT
The monitor is a 30 inch cinema display.
I am having a strange issue in photoshop. After a few hours of using photoshop CS5 the monitor starts flashing a greyscale pattern over the entire monitor. The pattern is a banded pattern that starts at light grey at the top of the monitor and goes toward black at the bottom. It is semi-transparent and I can see through it to the file and desktop beneath the pattern. The pattern pulsates very fast and is kind of hypnotic. The pattern does not go away and I quickly get the dreaded spinning beach ball and there is no way to escape from it without manually shutting down the computer as I can't force quit photoshop or move out of photoshop. Other times when I double click on a psd file to open in photoshop, the file appears scrambled and I can see the palettes inside of it all jumbled up, but this doesn't happen too frequently and more often I get the flashing gradient pattern that goes from black to white that I described earlier. The problem occurs on different files and is not confined to one user. It can start from asking photoshop to do the simplest thing like duplicate a file or create a new document.
These are the steps I have taken so far:
I have had Apple replace the video card but the problem still reoccurs. I have uninstalled and reinstalled CS5 and that did not solve the issue. I have run an extended hardware test which my computer passed. I have installed the update to photoshop which came out last week.
I think it is called 12.0.1.
The technician who replaced the video card mentioned that Adobe still uses an older technology that scrambles the files all over the computer. I am wondering if this is causing the problem.
What can I do? I am desperate. Adobe does not acknowledge the problem when I call or blames it on a faulty video card. The problem only occurs when I run Adobe CS5. It did not occur in CS3 which I owned before upgrading.
Please help. Thanks.
