Troubleshoot system errors or freezes (Photoshop 7.x, CS on Windows XP)
What's covered
Beginning troubleshooting
Intermediate troubleshooting
Advanced troubleshooting
This document can help you resolve system errors that occur when you use Adobe Photoshop on Windows XP. System errors can manifest themselves in many different ways, including (but not limited to) the following:
-- A blank or flickering dialog box
-- A frozen cursor or screen
-- An error such as
- "This program has performed an illegal operation and will be shut down. If the problem persists, contact the program vendor."
- "Photoshop caused a General Protection Fault in module [filename]."
- "Photoshop caused an Invalid Page Fault in module [filename]."
- "Application Error."
- "Unhandled exception detected. Application will be terminated."
- "Illegal Instruction."
- "Segment load failure in [filename]."
- "Unable to initialize Photoshop because of a program error."
- "Windows encountered a handling violation, no entry point found."
- "Unrecognized Handle Error"
Different factors can cause system errors, including conflicts among device drivers, software, and hardware, and corrupt elements in specific files. Although a system error may occur only when you work with Photoshop, Photoshop may not necessarily be the cause--it may be the only application that is memory- or processor-intensive enough to expose the problem.
To get the most from this document, perform the tasks in order. Keep track of the tasks you perform and the results of each, including errors or other problems. Adobe Technical Support can use this information to better assist you, should you need to call.
Note: The procedures in this document are based on the default interface of Windows XP. If the interface has been customized, some procedures may vary.
Beginningtroubleshooting
The tasks in this section can help you resolve the most common system errors. Before performing any of these tasks, back up all personal files (for example, Photoshop files you created). Always restart the computer after a system error occurs to refresh its memory. Continuing to work without restarting the computer may compound the problem.
Note: Some of these tasks require you to locate hidden files, and files by their full filenames, which include extensions (for example, filename.ini). By default, Windows Explorer hides hidden files, and filename extensions it recognizes. To enable Windows Explorer show hidden files and extensions, see your Windows documentation.
1. Make sure that the system meets the minimum requirements for Photoshop.
Photoshop may not run correctly if the system doesn't meet the following requirements:
Photoshop CS (purchased as a stand-alone product)
-- Intel Pentium III or 4 processor
-- Microsoft Windows 2000 with Service Pack 3 or Windows XP
-- 192 MB of RAM (256 MB recommended)
-- 280 MB of available hard-disk space
-- Color monitor with 16-bit color or greater video card
-- 1024 x 768 or greater monitor resolution
-- CD-ROM drive
-- Internet or phone connection required for product activation
Photoshop CS (purchased as a component of Adobe Creative Suite)
-- Intel Pentium III or 4 processor
-- Microsoft Windows 2000 with Service Pack 3 or Windows XP
-- 192 MB of RAM to run any one component (256 MB recommended)
-- Additional RAM required to run multiple components simultaneously
-- Additional 128 MB of RAM required to run Version Cue desktop server
-- 1.975 GB of available hard-disk space to install the entire suite*
-- 1024 x 768 monitor resolution with 16-bit or greater video card (24-bit screen display recommended)
-- CD-ROM drive
-- For Adobe PostScript printing: Adobe PostScript Level 2 or PostScript 3
-- Internet or phone connection required for product activation
-- QuickTime 6.3 required for multimedia features
*Premium edition only; 1.3 GB of available hard-disk space required for Standard edition.
Photoshop 7.0
-- Intel Pentium class III or 4 processor
-- 128 MB of RAM (192 MB recommended)
-- 280 MB of available hard-disk space
-- 800 x 600 color monitor with 16-bit color or greater video card
To check how much RAM is installed, choose Start > Control Panel, and double-click System. The amount of RAM appears on the lower half of the General panel in the System Properties window.
2. Install the latest version of Photoshop.
The latest version of Photoshop may be more compatible with the operating system and hardware drivers. Before you install an update or upgrade, make sure that your system meets the requirements.
The free Photoshop 7.0.1 update is available from the Adobe website at www.adobe.com/support/downloads/main.html. An upgrade, however, may solve a wider range of problems. (You may prefer to try the tasks in the rest of this document before upgrading.) You can purchase upgrades from Adobe authorized resellers and from Adobe directly:
-- To locate an authorized reseller, visit the Adobe website at http://store.adobe.com/store/customerregistration/other_places.jhtml or call Customer Services at 800-833-6687.
-- To purchase an upgrade from Adobe, visit the Adobe Store at http://store.adobe.com/store/products/master.jhtml?id=catPhotoshop or call Customer Services at 800-833-6687.
3.Install the latest Windows update.
Updates to Windows improve its performance and compatibility with other applications. You can obtain Service Packs from the Microsoft website at www.microsoft.com. For assistance installing a service pack, contact Microsoft Technical Support.
If you've reinstalled an application or Windows after installing the latest Service Pack, reinstall the Service Pack. Some applications install commonly used system files, overwriting the updated versions installed by the service pack.
4. Re-create the Photoshop preferences file.
Photoshop stores information about plug-ins, features, and the application itself in its primary preferences file. Re-create the primary Photoshop preferences file to eliminate problems a damaged preferences file might cause. If re-creating the primary Photoshop preferences file doesn't resolve the problem, remove all Photoshop preferences files. If the problem continues, the preferences file isn't the cause.
To re-create the primaryPhotoshop preferences file:
1. Exit from Photoshop.
2. Locate the Adobe Photoshop [version] Prefs.psp file in the Documents and Settings\[user profile]\Application Data\Adobe\Photoshop\[version]\Adobe Photoshop [version] Settings folder.
3. Rename the file (for example, to Adobe Photoshop [version]Prefs.old).
4. Start Photoshop. Photoshop creates a new primary preferences file.
To restore custom settings, delete the new primary preferences file and restore the original name of the previous primary preferences file.
To remove all preferences files for Photoshop and retain the option to recover them:
1. Exit from Photoshop.
2. Locate the Adobe Photoshop [version] Settings folder.
3. Rename the folder to Old Adobe Photoshop [version] Settings.
4. Start Photoshop. Photoshop creates new preferences files.
Note:If you need to use any of the old preferences files, delete the specific file in the Adobe Photoshop [version]Settings folder, and drag the file of the same name from the Old Adobe Photoshop [version] Settings folder into the Adobe Photoshop [version]Settings folder. Using old preferences files might cause the problem to recur.
To permanently delete all preferences files for Photoshop:
1. Exit from Photoshop.
2. Start Photoshop, and press Ctrl+Alt+Shift while Photoshop starts.
5.Run Photoshop while no other applications run in the background.
Some applications that run in the background may cause system errors or freezes when running concurrently with Photoshop. You can identify these applications and disable them before starting Photoshop. To identify problematic applications that run in the background, remove applications from the Startup folder, and close those that are specified in the registry to start automatically.
To disable startup items:
1. Exit from all applications.
2. Choose Start > Run, and type msconfig in the Open text box. Click OK.
3. Click the Startup tab, and select Disable All.
4. Select any startup items that are essential for testing the problem (for example, acrotray.exe is essential for creating PDF files with Acrobat). If you are unsure whether an item is essential, leave it deselected (disabled).
5. Click OK, and restart Windows.
6. Right-click to close or disable any items in the Notification Area (called the System Tray in earlier versions of Windows).
Then, try to re-create the problem:
-- If the problem doesn't occur, one of the startup items conflicts with Acrobat. Reenable startup items one at a time, testing each time until you determine which item conflicts with Acrobat. Then contact that item's developer for an update, if available.
-- If the problem recurs, startup items aren't the cause and you can reenable them:
a. Choose Start > Run, and type msconfig in the Open text box. Click OK.
b. Click the Startup tab, and select Enable All.
c. Click OK, and restart Windows.
6.Set a PostScript printer as the default.
To determine if the printer driver for the current default printer conflicts with Photoshop, install a printer that uses a PostScript printer driver, and then set that printer as the default. (In Windows, you can install a printer that isn't a physical piece of hardware.) If the problem doesn't recur, the printer driver that you were using previously conflicts with Photoshop; contact the printer manufacturer for an updated driver.
To install a printer that uses a PostScript printer driver:
1. Download the installer for the Adobe PostScript printer driver (AdobePS) from the Adobe website at www.adobe.com/support/downloads/pdrvwin.htm .
2. Double-click the installer file, and then follow the on-screen instructions.
To set a printer as the default:
1. Choose Start > Printers and Faxes.
2. Right-click the printer, and then choose Set as Default Printer from the pop-up menu.
7.Troubleshoot third-party plug-ins.
Remove third-party plug-ins from the Photoshop plug-ins folder, and then restart Photoshop. If the problem recurs, move the plug-ins back to the Photoshop plug-ins folder, and proceed to the next section of this document, "Intermediate troubleshooting." If the problem doesn't recur, identify and address conflicting plug-ins.
To identify and address conflicting plug-ins:
1. Move one third-party plug-in back to the Photoshop plug-ins folder.
2. Restart Photoshop and try to re-create the problem:
-- If the problem doesn't occur, repeat steps 1-2.
-- If the problem recurs, contact the developer of the plug-in you last moved to inquire about an update.
Intermediate troubleshooting
If the tasks in the previous section don't solve the problem, try the following intermediate troubleshooting tasks.
8.Reinstall Photoshop in Safe mode.
Device drivers and software that loads automatically with Windows (for example, screen savers, virus protection utilities) can conflict with the Photoshop installer. To prevent conflict, reinstall Photoshop while Windows is in Safe mode, which disables nonstandard device drivers and startup software.
To reinstall Photoshop in Safe mode:
1. Move any personal files out of the Photoshop folder and its subfolders.
2. Choose Start > Control Panel, and double-click Add/Remove Programs.
3. Select Photoshop, and click Remove. Follow the on-screen instructions to uninstall Photoshop.
4. Restart Windows and do one of the following:
-- Press the F8 key when you receive the message "Please select the operating system to start."
-- Press the F8 key as the computer restarts.
5. Select Safe Mode from the Windows Advanced Options menu.
6. Insert the Photoshop CD-ROM, and install Photoshop.
7. Restart Windows.
9.Update the video driver.
Many manufacturers of video display adapters frequently update their software drivers. If you haven't updated the display adapter driver recently, contact the video card manufacturer for an updated driver, or download one from the manufacturer's website. (To determine the manufacturer of the video card, view the card's properties in Device Manager.) You can often determine if the video driver is outdated by changing the color-depth and resolution of the video card or by disabling graphics hardware acceleration.
To change the color-depth and resolution:
1. Choose Start > Settings > Control Panel, and then double-click Display.
2. Click the Settings tab.
3. Change the color depth using the Color quality menu:
- If the current color depth is 16-bit or 32-bit, choose True Color (which may be designated as 24-bit color; 16,777,216 colors; or millions of colors).
- If the current color depth is True Color, choose 16-bit or 32-bit color.
4. Change the resolution using the Screen resolution menu:
- If the current resolution is 1024 x 768, move the slider to a different resolution, such as 800 x 600 or 1280 x 1024.
- If the current resolution is not 1024 x 768, move the slider to 1024 x 768.
Note: Although Photoshop CS requires a screen resolution of at least 1024 x 768, you may test your video card driver by temporarily using the resolution of 800 x 600. At this setting, however, you won't see the entire Options bar.
5. Click Apply, and then click OK.
6. Restart Windows and Photoshop. If changing the color-depth and resolution of the video card fixes the problem, contact the video card manufacturer for an updated driver.
To disable graphics hardware acceleration:
1. Choose Start > Settings > Control Panel.
2. Double-click Display, click the Settings tab, and then click Advanced.
3. Click the Troubleshooting tab.
4. Move the Hardware acceleration slider to None.
5. Click OK to accept the new setting, and then click OK to close the Display Properties window.
6. Restart Windows and Photoshop. If the problem no longer occurs, contact the video card manufacturer for an updated driver.
10.Verify that other device drivers are compatible with Windows XP.
If updating the video card driver doesn't resolve the problem, verify that all other device drivers are compatible with Windows XP. Device drivers are software files that allow Windows to communicate with devices such as scanners, mouse devices, and keyboards. Contact the device manufacturer to make sure that you are using the latest driver for it.
To check for device driver problems:
1. Choose Start > Control Panel, and then double-click System.
2. Click the Hardware tab, and then click Device Manager.
3. Click the plus sign (+) to the left of each device type.
4. If a device appears with a black exclamation mark (!) in a yellow circle, right-click that device, and choose Properties from the pop-up menu.
5. Note the properties for the device:
-- Check the Device Status field: If the device isn't working properly, information in this field can help you troubleshoot the problem.
-- If the Properties dialog box has a Driver tab, click it. If the Driver tab doesn't indicate the driver provider, click Driver Details. If Microsoft is the provider, a generic driver is probably installed; contact the device manufacturer to obtain the most recent driver they provide.
11.Setthe virtual memory paging file to the defaultsize.
Virtual memory allows the system to use hard disk space to store information normally stored in memory (RAM). Windows XP manages virtual memory using a paging file; you define the minimum and maximum size of this file. If the size is different from the default in Windows XP, applications may return errors. Some applications, however, may require a nondefault size for the paging file, so change the size only if other applications aren't adversely affected.
To set the paging file to the default size:
Note:You must be logged on as an Administrator to change the size of the paging file.
1. Exit from open applications.
2. Choose Start > Control Panel, and then double click System.
3. Click the Advanced tab, and then click Settings in the Performance section.
4. Click the Advanced tab, and then click Change in the Virtual Memory section.
5. From the Drive list, select a hard drive that has free space equal to at least 1.5 times the amount of the computer's installed RAM. To determine the amount of space available on a drive, click the drive letter; the amount of space available appears in the Paging File Size for Selected Drive section.
6. In the Initial Size text box, enter a value equal to one and a half times the amount of the computer's installed RAM.
7. In the Maximum Size text box, enter the same value you entered for Initial Size.
8. Click Set, and then click OK to close the Virtual Memory dialog box.
9. Click OK when Windows returns the alert "The changes you have made require you to restart your computer . . ."
10. Click OK to close the Performance Options dialog box, and then click OK to close the System Properties dialog box.
11. Click Yes in the System Settings Change dialog box. Windows restarts.
12.Optimize handling of temporary files by Windows.
Windows and applications store working data in temporary (*.tmp) files that they create on the hard disk. Excessive or outdated temporary files can interfere with performance of Windows or applications. Delete temporary files, and make sure that at least 280 MB of free space is available on the hard disk to which they are written.
To delete temporary files:
1. Exit from open applications.
2. Choose Start > Search, and then click All Files or Folders.
3. Type *.tmp in the All or Part of the File Name text box.
4. Choose Local Hard Drives from the Look In pop-up menu, and then click Search.
5. After the search results appear, choose Edit > Select All.
6. Choose File > Delete. Click Yes to confirm that you want to send the files to the Recycle Bin.
7. Remove any files you don't want to delete from the Recycle Bin, and then empty the Recycle Bin. Windows deletes all temporary files not in use.
To make sure that at least 280 MB of free space is available on the hard disk to which temporary files are written:
1. Exit from open applications.
2. Choose Start > Control Panel, and then double-click System.
3. Click the Advanced tab, and then click Environment Variables.
4. In the User variables for [user profile] section, locate TEMP in the Variable column, and note the folder listed in the Value column. If the complete pathname for the folder isn't visible, double-click TEMP in the Variable column, and note the folder name in the Variable Value text box.
Note: If a TEMP variable doesn't exist, contact your system administrator for assistance.
5. In Windows Explorer, verify that the folder you noted in step 4 exists on a noncompressed drive that has at least 280 MB of free space:
-- If the folder doesn't exist, create it: Right-click the drive, choose New Folder from the pop-up menu, and type the folder name you noted in step 4 (for example, Temp).
-- If the drive doesn't have enough free space, create additional space by removing unnecessary files. To determine the amount of free space, right-click the drive and choose Properties from the pop-up menu.
Note: Windows requires at least 115 MB of free space on the hard-disk on which it is installed in order to work properly (even if Photoshop is installed on a different drive).
13.Optimize scratch disks.
When insufficient RAM is available for bitmap image editing, Photoshop uses a scratch disk file--temporary disk space used for storing data and performing computations. Photoshop CS can create 64 exabytes of scratch disk files on up to four hard disk partitions, while Photoshop 7 can create 4 exabytes of scratch disk files on up to four hard disk partitions. An exabyte is 1.074 billion gigabytes.
The partitions you specify as the scratch disks should have enough free space to hold data several times the size of your image. A rule of thumb for good performance is to have free space equal to three to five times the size of the average image file. If disk space is insufficient, delete temporary files (see task 5) or remove other files from the hard disks.
To specify a scratch disk in Photoshop, choose Edit > Preferences > Plug-ins & Scratch Disks.
14. Repair and defragment hard disks.
System errors can occur if hard disks contain damaged sectors or fragmented files. Repair and defragment hard disks using either the Error-checking tool and Disk Defragmenter utility included with Windows or a third-party disk utility (for example, Norton Utilities from Symantec). You should run such utilities on each hard disk or partition. More information about the Error-checking tool and Disk Defragmenter appears below; for more information about a third-party disk utility, refer to the documentation for the utility.
The Error-checking tool repairs bad sectors, lost allocation units and file fragments, cross-linked files, and invalid file names. To access the Error-checking tool, choose Start > My Computer, right-click the desired hard disk, and choose Properties from the pop-up menu; in the Local Disk Properties dialog box, click the Tools tab, and then click Check Now in the Error-checking section.
Note: To prevent Disk Defragmenter from moving files to bad sectors of a disk, run the Error-checking tool before running Disk Defragmenter.
Disk Defragmenter rearranges the files and free space on your computer so files are stored in contiguous units and free space is consolidated in one contiguous block. To access the Disk Defragmenter utility, choose Start > All Programs > Accessories > System Tools > Disk Defragmenter.
15. Disable the MMXCore and FastCore plug-ins.
The MMXCore and FastCore plug-ins enable Photoshop to take advantage of MMX technology. If your processor doesn't support MMX technology, system errors can occur. To prevent such errors, disable the MMXCore and FastCore plug-ins.
Note: Although Photoshop can run without the MMXCore and FastCore plug-ins, some of its functions will be slower.
To disable the MMXCore and FastCore plug-ins:
1. Exit from Photoshop.
2. In Windows Explorer, locate the MMXCore.8bx and FastCore.8bx plug-ins in the Program Files\Adobe\Photoshop [version]\Plug-Ins\Adobe Photoshop Only\Extensions folder.
3. Rename the plug-ins to MMXCore.old and FastCore.old.
4. Start Photoshop and try to re-create the error. If the error doesn't recur, rename the plug-ins back to MMXCore.8bx and FastCore.8bx, and then proceed to the next task.
16. Check for font problems.
To determine whether a font causes the problem, reduce the number of active TrueType fonts by moving the font files to another location:
Note: Don't move the TrueType fonts installed by Windows. For a list of these fonts, see326402 , "TrueType Fonts Installed by Windows XP."
1. Create a new folder (for example, C:\TrueType).
2. Open the Windows\Fonts folder.
3. Move TrueType font files, excluding those installed by Windows, from the Windows\Fonts folder to the folder you created in step 1.
4. Restart Windows.
5. Move a few of the fonts from step 3 back to the Windows\Fonts folder.
6. Restart Windows.
7. Start Photoshop, and try to re-create the problem:
-- If the problem recurs, one of the fonts you moved in step 5 may be the cause. Remove those fonts from the Windows\Fonts folder, and repeat steps 4-6, this time adding only one font at a time. When the problem recurs, do one or more of the following:
- If you use a font utility other than the Windows Fonts folder (for example, FontMaster 6.0, included with CorelDRAW 6.0), remove the fonts using that utility. For instructions, refer to the documentation for the utility.
- Remove the font and reinstall it from the original media.
- Contact the font manufacturer to obtain an updated version of the font.
-- If the problem doesn't recur, repeat steps 5-7, testing different fonts.
17. Scan the system for viruses.
Use current anti-virus software (for example, Symantec Norton AntiVirus, McAfee AntiVirus) to check the system for viruses. Virus infections can damage software and cause system errors. For more information, see the documentation for the anti-virus software.
18.Run Photoshop using a different user account.
Create a new user account that has the same permissions as the account you use when the problem occurs. If the problem doesn't recur, the original user account may be damaged. For information on setting up a user account, see the Windows XP documentation or contact your network administrator.
19. If you upgraded to Windows XP, perform a clean installation of Photoshop.
If you installed Windows XP over a different version of Windows, the Photoshop files, or one or more Photoshop entries in the Windows registry, may be damaged. To ensure that those items aren't damaged, remove all versions of Photoshop, all remaining Photoshop files, and all Photoshop entries from the registry. Then reinstall Photoshop in Safe mode, following steps 1-4 in the first step in the Intermediate Troubleshooting section.
To remove all versions of Photoshop, all remaining Photoshop files, and all Photoshop entries from the registry:
a. Move any personal files out of all Photoshop folders and their subfolders.
b. Use the Add or Remove Programs utility in Control Panel to remove all versions of Photoshop. (Do not remove Photoshop Elements.)
c. Remove any Photoshop folders from the following folders (do not delete any Photoshop Elements folders):
-- Program Files\Adobe
-- Documents and Settings\[username]\Application Data\Adobe\FileBrowser
-- Documents and Settings\[username]\Application Data\Adobe\ImageReady
-- Documents and Settings\[username]\Application Data\Adobe\Photoshop
d. Delete the Workflow folder from the Documents and Settings\[username]\Application Data\Adobe folder.
e. Delete all ImageReady and Photoshop registry keys:
Disclaimer: This procedure involves editing the Windows registry. Adobe does not support editing the registry, which contains critical system and application information. Make sure to back up the registry before editing it. For more information about the registry, refer to the Windows documentation, or contact Microsoft.
i. Choose Start > Run.
ii. In the Open text box, type regedt32. Click OK to open the Registry Editor.
iii. Back up the registry: Choose File > Export, and select a name and location for the back-up registry. Select All in the Export Range section, and click Save.
iv. In the left pane of the Registry Editor, click HKEY_LOCAL_MACHINE.
v. Click Software, and then click Adobe.
vi. Delete all Photoshop and ImageReady folders.
f. Empty the Recycle Bin.
g. Restart Windows XP.
20.Identify the filethat causes the problem.
If an error indicates which file causes the problem, reinstall the application to which that file belongs. If that file is damaged and causes problems in Photoshop, reinstalling the associated application can correct the problem.
If an error indicates a Windows file, contact Microsoft for help replacing that file. If the problem persists, proceed to task 21.
Advanced troubleshooting
If the tasks in the previous section don't resolve the problem, hardware may be conflicting with Photoshop. The following procedures will help you isolate a hardware conflict.
Disclaimer: Adobe doesn't support hardware and provides these tasks as a courtesy only. For further assistance, contact the hardware manufacturer or an authorized reseller. If you troubleshoot hardware problems yourself, you may void the warranty for your computer.
Note: Before you remove or rearrange hardware, turn off the power to the computer and any peripherals.
21. Reformat the hard disk, and reinstall only Windows XP and Photoshop.
Reformat the hard disk, and then install only Windows XP and Photoshop from the original installation media. Reformatting a disk erases all files it contains, so be sure to back up all personal files first. Also make sure that you have all application and system disks.
Note: Don't install additional software or hardware until you're sure that the problem is resolved. Don't back up the hard disk and restore Windows and Photoshop instead of reinstalling them; if the problem is caused by an application or Windows, and either one is restored instead of reinstalled, the problem may recur.
After you reformat the hard disk and reinstall Windows and Photoshop, try to re-create the problem:
-- If the problem no longer occurs, install other applications one at a time and try to re-create the problem after each installation. If the problem occurs after an installation, the recently installed application may be the cause.
-- If the problem occurs when only Windows and Photoshop are installed, the cause is hardware-related, and you should contact the hardware manufacturer or an authorized reseller for assistance. Before contacting the manufacturer or reseller, however, you may want to try one or more of the following tasks.
22.Check for SCSI problems.
If you have a SCSI card for internal or external SCSI devices, verify that the settings for the card are correct, ensure that the SCSI chain is properly terminated, update SCSI drivers, and check for hardware or cable damage. For instructions, contact the SCSI card manufacturer.
You can also check for SCSI problems by using the System Properties dialog box:
1. Choose Start > Control Panel, and double-click System.
2. Click the Hardware tab, and then click Device Manager.
3. Click the plus sign (+) to the left of the SCSI and RAID Controllers line.
4. For each adapter listed, right-click the name, and then choose Properties from the pop-up menu. If the Device Status section indicates that the SCSI adapter isn't working correctly, reinstall SCSI device drivers; contact the SCSI card manufacturer for further help.
23. Check for problems with RAM SIMMs or DIMMs.
Ensure that the RAM SIMMs or DIMMs are installed properly and are not the cause by doing one or more of the following:
-- Change the order of the installed SIMMs or DIMMs.
-- Remove all but the minimum number of SIMMs or DIMMs needed to run Windows and Photoshop, and test to see if the problem persists. If it does, replace the SIMMs or DIMMs you removed and remove the others, testing again to see if the problem recurs. If it doesn't, one or more of the removed SIMMs or DIMMs are the cause. For assistance, contact the RAM SIMM or DIMM manufacturer.
