Problem:
The instructions at "0×000000" referenced memory at "0×00000000". The memory could not be "written"
I would get this error message when I was trying to open a program such as Adobe, Winamp, Office, Firefox, etc. Here is how I fixed the error message…
Fix:
First lets verify that this fix will get rid of this error message for you.
First go to – Control Panel, Open up System, Click on the Advanced tab – then Performance Setting, then Data Execution Prevention Tab. if this screen is not grayed out and instead has a box checked – to turn on DEP- then chances are this is the root of your problems and this fix will work for you.
So turn off DEP and fix your problem, follow the next 8 steps…..
Step 1: Go to Start, Run, and type in cmd ( for dos command prompt ) and then type in cd\ and press enter to go to the root directory ( Typically c:\ )
Step 2: type in
attrib -r -h -s boot.ini
Step 3: type in
edit boot.ini
and press enter
Step 4: Find the line that looks like this or similar to this
multi<0>disk<0>rdisk<0>partition<1>\windows="Microsoft Windows" /fastdetect /NoExecute=
Step 5: NoExcute= can be set to four different settings.
/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.
You want to set this to NoExecute=AlwaysOff to disable DEP
Example Corrected Boot.ini Line -
multi<0>disk<0>rdisk<0>partition<1>\windows="Microsoft Windows" /fastdetect /NoExecute=AlwaysOff
Step 6: Save the file and exit the edit boot.ini screen and return to the Command Prompt
Step 7: You now want to restore the old Attrib settings back to boot.ini so type in
attrib +h +r +s boot.ini
Step 8: Now restart your computer and the error should never come back
