Windows shuts down the suite reporting DEP to protect computer

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:

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.

To determine the current DEP support policy, 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_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.

DataExecutionPrevention_SupportPolicy property valuePolicy LevelDescription2OptIn (default configuration)Only Windows system components and services have DEP applied3OptOutDEP is enabled for all processes. Administrators can manually create a list of specific applications which do not have DEP applied1AlwaysOnDEP is enabled for all processes0AlwaysOffDEP is not enabled for any processesNote To verify that Windows is running with hardware DEP enabled, examine the DataExecutionPrevention_Driversproperty 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. 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:

1. Click Start, click Run, type wbemtest in the Open box, and then click OK.
2. In the Windows Management Instrumentation Tester dialog box, click Connect.
3. In the box at the top of the Connect dialog box, type root\cimv2, and then click Connect.
4. Click Enum Instances.
5. In the Class Info dialog box, type Win32_OperatingSystem in the Enter superclass name box, and then click OK.
6. In the Query Result dialog box, double-click the top item.
   
   Note This item starts with "Win32_OperatingSystem.Name=Microsoft..."
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.

"An application error has occurred and an application error log is being generated. Exception: access violation (0xC0000005), Address"

The error 0xC0000005 is generated by an illegal "memory access violation". This can be caused by anything from faulty RAM, an incorrect/corrupt device driver, poorly written/updated software and more commonly under Windows XP Service pack 2, malware/adware installations.

Usually you get this error message when performing a specific task, and if that happens you need to check the corresponding 3rd party's website/support department to see if they are aware of the problem

..a while back Symantec Antivirus caused the 0xC0000005 error with an additional message about a file called SAVRT.SYS . A simple software update to the Symantec Antivirus cured the problem.

So what can you do...? well below are a couple of suggestions:



0xC0000005 - Resolution Suggestion One:

In many cases this error has been generated by faulty RAM memory. So if you have just upgraded your computer with some new memory and you started getting this error then I would remove them and see if the error goes away. If it does then send the memory back and get a refund!


0xC0000005 - Resolution Suggestion Two:

In Windows XP Service Pack 2 Microsoft introduced Data execution prevention (DEP), a set of hardware and software technologies that perform additional checks on memory to help protect against malicious code exploits. In Windows XP SP2, DEP is enforced by both hardware and software.

Some software/application behaviours are incompatible with DEP - data execution prevention. Applications which perform dynamic code generation (such as Just-In-Time code generation) and that do not explicitly mark generated code with Execute permission might have compatibility issues with data execution prevention. Applications which are not built with SafeSEH must have their exception handlers located in executable memory regions.

Applications that attempt to violate DEP will receive an exception with status code STATUS_ACCESS_VIOLATION (0xC0000005).

If an application requires executable memory, it must explicitly set this attribute on the appropriate memory by specifying PAGE_EXECUTE, PAGE_EXECUTE_READ, PAGE_EXECUTE_READWRITE or PAGE_EXECUTE_WRITECOPY in the memory protection argument of the Virtual* memory allocation functions.

If you are having issues with 0xC0000005 errors in DEP and a particular piece of software is causing the offence, contact the vendor for a resolution...

Note: It is possible to "Turn Off" DEP in the boot.ini file but this really would be a last step!

/NOEXECUTE

This option is only available on 32-bit versions of Windows when running on processors supporting no-execute protection. It enables no-execute protection (also known as Data Execution Protection - DEP), which results in the Memory Manager marking pages containing data as no-execute so that they cannot be executed as code. This can be useful for preventing malicious code from exploiting buffer overflow bugs with unexpected program input in order to execute arbitrary code. No-execute protection is always enabled on 64-bit versions of Windows on processors that support no-execute protection.

There are several options you can specify with this switch:

/NOEXECUTE=OPTIN Enables DEP for core system images and those specified in the DEP configuration dialog.

/NOEXECUTE=OPTOUT Enables DEP for all images except those specified in the DEP configuration dialog.

/NOEXECUTE=ALWAYSON Enables DEP on all images.

/NOEXECUTE=ALWAYSOFF Disables DEP. (This setting doesn't provide any DEP coverage for any part of the system, regardless of hardware DEP support. The processor doesn't run in Physical Address Extension (PAE) mode unless the /PAE option is present in the boot.ini file.)

0xC0000005 - Resolution Suggestion Three:

I have also seen this error in the gaming community when folks have updated drivers for their graphics card. If this happens just roll back your drivers and then "Google" to see if their are any other folks reporting this issue. Also keep an eye on the vendors website to see if they have an update/patch available or coming soon.



0xC0000005 - Resolution Suggestion Four:

Microsoft Internet Explorer 6.0 stops responding when you try to open an HTML document or a Web page. Additionally, you receive the following error message:
Access Violation (0xC0000005 exception)

CAUSE:

This problem may occur when you use Internet Explorer 6.0 to open an HTML document or a Web page that contains SPAN tags. If a SPAN tag is not closed correctly by using the tag, an access violation may occur.

In many cases this error has been generated by faulty RAM memory. So if you have just upgraded your computer with some new memory and you started getting this error then would remove them and see if the error goes away. If it does then send the memory back and get a refund!

Having DEP is a "good" thing -- your RAM holds "instructions" (such as 'add' or 'multiply') and it holds "data" ('1', 'cat', '2', 'dog').

DEP recognizes the difference between "instructions" and "data", and REFUSES to take a "data" value, and try to interpret as an "instruction". This "prevention" blocks some computer-viruses!

Right click on My Computer and select Properties.
Click on Advanced System Settings
Click on Advanced tab
Click on Settings button under Performance
Click on the "Data Execution Protection" tab
Select "Turn on DEP for essential Windows programs and services only"
Click on Apply and OK.

hi there, The error 0xC0000005 is generated by an illegal "memory access violation". This can be caused by anything from faulty RAM, an incorrect/corrupt device driver, poorly written/updated software and more commonly under Windows XP Service pack 2, malware/adware installations.

i would suggest that the ram in your computer has possibly broken down over a period, may i recommend obtaining some new ram, if you go to www.crucial.com they can provide you with information that tells you which ram you have in your PC.
