Hi there,

Hope someone can help me out!

Whenever I click on explorer or try to access any folders on the C: or E: (second hard disk) drives, I get the message:

"Data Execution Prevention - Microsoft Windows

To help your computer, windows has closed this program"

I have gone on to the microsoft site and read up about this but to be honest, I haven't really got a clue what it's talking about or how I can solve this.

Could anyone possibly explain what might be the issue and how I can find out what's causing this.

Really appreciate it!

Cheers!

Rick

Hello rsedsy,

Welcome to PCHF.

- Go to My Computer, Control Panel, System.
- Click on the Advanced tab, and click Settings under "Performance".
- Click on the Data Execution Prevention tab, and you will see the following window:



- Make sure your settings match the widow above, then Apply and reboot your PC.

Cheers Madmonkey - really appreciate it!

The settings all matched what you posted above and i've rebooted.

Where do we go from here?

OK, next,

- Go to Start, Run and type notepad.exe
- OK, then go to File, Open.
- In the filename type c:\boot.ini

Please can you Copy and Paste the contents of this file here.

Here you go....

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOW S
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Micro soft Windows XP Professional" /noexecute=optin /fastdetect

Right OK.

- Go back to the Performance Options window I showed earlier, Data Execution Prevention.
- Change option to Turn on DEP for all programs and services except those I select.
- Finally, put a check in Windows Explorer, and OK those changes.
- Reboot, and test!

That was easy in the end!

I did exactly what you said and it's working perfectly now!!

Really appreciate you taking the time out so thanks very much.

Take it easy,

Rick
