My google chrome crashed and everytime i click on it a message says DEP has closed it


To use hardware-enforced DEP, you must meet all the following conditions:
  1. The computer's processor must support hardware-enforced DEP.

    Many recent processors support hardware-enforced DEP. Both Advanced Micro Devices (AMD) and Intel Corporation have defined and shipped Windows-compatible architectures that are compatible with DEP. This processor support may be known as NX (no-execute) or XD (execute disable) technology. To determine whether your computer's processor supports hardware-enforced DEP, contact the manufacturer of your computer.
  2. Hardware-enforced DEP must be enabled in the BIOS.

    On some computers, you can disable processor support for hardware-enforced DEP in the BIOS. You must not disable this support. Depending on your computer manufacturer, the option to disable this support may be labeled "Data Execution Prevention," "XD," "Execute Disable," or "NX."
  3. The computer must have Windows XP with Service Pack 2 or Windows Server 2003 with Service Pack 1 installed.

    Note Both 32-bit versions and 64-bit versions of Windows support hardware-enforced DEP. Windows XP Media Center Edition 2005 and Microsoft Windows XP Tablet PC Edition 2005 include all the features and components of Windows XP SP2.
  4. Hardware-enforced DEP must be enabled for programs on the computer.

    In 64-bit versions of Windows, hardware-enforced DEP is always enabled for 64-bit native programs. However, depending on your configuration, hardware-enforced DEP may be disabled for 32-bit programs.
For more information about DEP, about DEP configuration, and for a list of Windows Operating Systems that support hardware DEP, click the following article number to view the article in the Microsoft Knowledge Base:875352 A detailed description of the Data Execution Prevention (DEP) feature in Windows XP Service Pack 2, Windows XP Tablet PC Edition 2005, and Windows Server 2003For information about how to configure memory protection in Windows XP with Service Pack 2, visit the following Microsoft Web site:

http://technet.microsoft.com/en-us/library/cc700810.aspx

To confirm that hardware DEP is working in WindowsTo confirm that hardware DEP is working in Windows, use one of the following methods.Method 1: Use the Wmic command-line toolYou can use the Wmic command-line tool to examine the DEP settings. To determine whether hardware-enforced DEP is available, follow these steps:
  1. Click Start, click Run, type cmd in the Open box, and then click OK.
  2. At the command prompt, type the following command, and then press ENTER:wmic OS Get DataExecutionPrevention_AvailableIf the output is "TRUE," hardware-enforced DEP is available.

  2. At the command prompt, type the following command, and then press ENTER:wmic OS Get DataExecutionPrevention_SupportPolicyThe value returned will be 0, 1, 2 or 3. This value corresponds to one of the DEP support policies that are described in the following table.

In some system configurations, hardware DEP may be disabled by using the /nopae or /execute switches in the Boot.ini file. To examine this property, type the following command at a command prompt:wmic OS Get DataExecutionPrevention_DriversMethod 2: Use the graphical user interfaceTo use the graphical user interface to determine whether DEP is available, follow these steps:

  7. In the Object editor dialog box, locate the DataExecutionPrevention_Available property in the Properties area.
  8. Double-click DataExecutionPrevention_Available.
  9. In the Property Editor dialog box, note the value in the Value box.
If the value is TRUE, hardware DEP is available.Notes
  • To determine the mode in which DEP is running, examine the DataExecutionPrevention_SupportPolicy property of the Win32_OperatingSystem class. The table at the end of Method 1 describes each support policy value.
  • To verify that hardware DEP is enabled in Windows, examine the DataExecutionPrevention_Drivers property of the Win32_OperatingSystem class. In some system configurations, hardware DEP may be disabled by using the/nopae or /execute switches in the Boot.ini file.

Window Vista problem??


If you receive this error message or encounter difficulties when attempting to launch Pro Tools using Windows Vista disabling DEP may solve the problem.

This option disables "Data Execution Prevention", a feature of Windows that can sometimes cause errors. This won’t harm anything, but also isn’t always necessary.

How to Disable DEP:

1. Click "Start"
2. Click "All Programs"
3. Click "Accessories"
4. Right Click on "Command Prompt"
5. Left click on "Run as Administrator"
6. Click the Allow button if it asks you for permission
7. Type or copy and paste this into the command prompt window:

bcdedit.exe /set {current} nx AlwaysOff


8. Hit enter and you should see the confirmation: Operation Completed Successfully
9. Reboot and DEP should be off.

If you would like to re-enable DEP enter the following into the command prompt window:
bcdedit.exe /set {current} nx AlwaysOn

Hit enter and you should see the confirmation: Operation Completed Successfully. After restarting the computer, DEP will be re-enabled.

Why do i keep getting DEP error message each time i close IE8 or a tab?


windows xp has DEP ( data execution prevention ) some viruses etc use that sort of technique and from SP2 onwards I believe it was they included it.

http://www.zensoftware.co.uk/kb/article.aspx?id=10002


Several OSs have no-execute or execute protection. Microsoft has added this as well in SP2 with data execution prevention (DEP). This precents code execution in memory regions already marked as storage. This is a powerful tool against buffer overrun exploits. If a program is failing and you want to disable DEP to see if that is the cause. Here are the steps. (Just disable DEP for the program in question… don’t disable it for your whole system.)
    1. Click Start
    2. Select Control Panel
    3. Select System
    4. Click the Advanced tab
    5. In the Performance region select Settings
    6. Click the Data Execute tab in the dialog box that opens
    7. Select Turn on DEP for all programs and services except for those I select
    8. Click Add.
    9. The open dialog box will open. Browse and select your application.
    10. Click Open
    11. Click Apply
    12. Click Ok
    13. Reboot
