Memory error

OS: Windows 7 x64 Ultimate
Ram: 4GB
Video Card: nVidia Gefore 8800 GTS 512mb
CPU: Core2Duo e8400

Photoshop CS4 v11.01

When using the marquee tool in Vanishing Point Photoshop crashes with either no error or

"The instruction at 0x******** referenced memory at 0x********. The memory could not be read. Click on OK to terminate the program"

I am also seeing SideBySide errors in the windows event viewer with these details

Here is one of the error details from when it just crashes (This is the one that shows up in event viewer after I uninstalled Acrobat 9.0)

I have tested each memory module with memtest86 3.5 and they turn up with no errors I have also tried completely removing Photoshop and reinstalling. Any help is much appreciated.


Edit: When I zoom in and use the marquee tool it almost instantly has a memory error but when at 100% it takes a few seconds and I have to move it back and forth.

resolved

Was starting to think that my computers RAM was going bad because over the past couple weeks of leaving my computer on over night it would freeze up when I tried to use it.

I then started to get could not read memory errors in vanishing point which led me to use memtest86

I then started up memtest86 and ended up with a few errors... not looking good right?

Turns out memtest86 doesn't handle multiple memory modules very well so I scanned them one at a time and got no issues.

I then found out after searching for the photoshop issue that if you have auto-hide taskbar enabled (which I enabled a couple weeks ago) your computer will freeze after being idle.

I then was left with the photoshop issue after doing the troubleshooting I mentioned previously I was at a loss until Iain(from a different forum) shot me a message about some Windows 7 issues so I started to disable some stuff and dwm.exe (the Desktop Window Manger) ended up being the culprit.

Long story short don't use auto-hide taskbar, scan one memory module at time with memtest86 and kill dwm.exe in Windows 7 atleast when using Photoshop. Hopefully these issues get patched soon.

Here is a quick guide to permanently disabling dwm.exe if you wish.. It will kill your pretty theme though. How to Speed up Vista Tips: Disable the Windows Desktop Manager (Tip #006) | eHow.com

P.S. This post is long winded because I hate when I come across a resolved issue post that either doesn't have an answer or not enough information.

Alternate ways of disabling dwm.exe

Disable it for just Photoshop ( Preferred Method )
1. Right click on your Photoshop shortcut and click "Properties"
2. Click the "Compatibility" tab and check "Disable desktop composition"
3. Click "Apply" and then "Ok"
Note: For me this only seems to be available for 32bit not the x64 executable which has the option grayed out. I have tried the registry hack and that doesn't seem to work so if anyone knows how to get x64 working please let me know.

Edit: A workaround is to set "Adobe Bridge" to disable desktop composition this works great if you use it if not maybe try to set another small application to disable it and run that when you will be using Photoshop x64.


Disable it permanently
1. Right click on my computer and click properties
2. Click "Advanced system settings" on the left side
3. Click the "Advanced" tab
4. Click "Settings" for "Performance"
5. Uncheck "Enable desktop composition"
6. Click apply and your done

Turns out memtest86 doesn't handle multiple memory modules very well so I scanned them one at a time and got no issues.

I don't know where you got that information, because it's totally false. All Memtest does is writing nothing but patterns to memory and reading them back. If you have errors with all modules in use, then they're obviously not working well together.
The fact that you got Photoshop to work doesn't change that.
